He huarahi pono ki te whakanui i te pūāhua pūngao he tuku ki te whakamahi hei pūnaha e kaha ana te whanonga e te punaha pūngao, te hoahoa pāmahana, te whakamahinga PCB, te rautaki whakamaru, me ngā poutū whakahaere. Ko ngā kōwhiringa taputapu (BJT vs MOSFET vs GaN) ka huri i ngā here me te wātea i ngā whai wāhitanga rerekē, engari ko te āhua o te mahi ia rā ka tino whakaritea e te rautaki pūtea, te ūnga poutū, me te pānui e te hoahoa i ngā uta pono me ngā āhuatanga whakahaere pono.

I roto i ngā hoahoa pono, he maha ngā wā ka whakawhirinaki te whakatutuki ki te āta whakahaere i kāore ki ngā kōwae whānui. Ko ngā take nui kei reira ko ngā ara hoki hiko, te hanganga tāwhati, te pānui whakakā, me te whakahaere pātea e ū ana i ngā panoni pāmahana. Ka āwhina ēnei kōrero ki te hanga i ngā pūāhua e noho ana i te pāmahana, e tika ana me te tauwhiro i te wā e whakamātau ana me te wā roa e mahi ana.

Ngā Kāwai Pūāhua Pūngao me Ngā Ōhākī Mahi

Ka wehewehe ngā pūāhua pūngao e ngā kāwai, he tohu e hāngai ana ki te koki whakahaere o ngā taputapu putanga i runga i te wā tohu. Ka tūtohu tēnei tohu ki te whiringa hoahoa hohonu: mēnā ka tūmanakohia ngā taputapu putanga ki te whanonga hei āhuatanga porowhita, hei pātea, hei tīwhiri i te hunga e rua.

I roto i ngā hua pono, kaore i te aituā te ingoa kāwai e taea te tupu ka riro te whakautu i te whakamatatini i a ia. Ka hanga te putanga e te whanonga o te hoahoa i te wā e tūpono ana ngā āhuatanga ki te kore e rērā, pērā i te pikinga pāmahana, te uta e noho ana he pātea, nāna anō hoki i te tauira hanga e kore e rahi. He maha ngā raru hoahoa uaua e pā ana ki te hūnuku āta, ngā āhuatanga raro, me ngā whakahaere stagnate, i reira ka mau tonu te whanonga pūnātea.

Ko te huarahi whakamārama i ngā kāwai pūāhua he pērā i te noho mai ki ngā pātai e rua:

• Kei hea te pūngao e mutu ana ki te waikawa ki ngā āhuatanga whakahaere?

• He aha te pupuri i te whanonga whakararu i te wā e pāmahana ana me te uta e neke ana?

Kāwai A

Kāwai A e pupuri ana i te taputapu putanga e whakahaere ana i te wa katoa o te huringa. Nā te mea kāore e tika ana te taputapu, kāore he wā whakawhiti i waenganui i ngā taputapu, e hiahiatia ana ka taea e te whakahaere Wiwi te painga i raro i te tikanga. I te wā e pātea ana te pūnaha, ka pūreretia te ngāwari o ngā tohu iti, ā, ko te wharangi whakararu ka noho ki te pātea me te pā.

Ka puta te dealahi i runga i te tātaritanga pūngao. Kāwai A ka tango i te hiko nui ahakoa i te nui, ā, ka tū te hiko hei pāmahana nāna e noho ana i te hihiri i whakaari ana. I te maha o ngā hoahoa motuhake, ka riro te pūngao i te hokohoko hei te āhuatanga whakawhitia kāore e noho ki te hoahoa pāmahana. He mea noa te rongo kāore e mau te i te ahurei i muri i te tātaritanga, ka whakatika i te whakaari e whakatauiratia tonu ana te pāmahana i ngā rangi kotahi.

Ka tau te whanonga pāmahana ki ngā kōrero ā-tinana e pā ana ki ngā kōrero i te kāhui ka pūrongo i ngā āhuatanga e māmā ana te whakamahi i te mōhio:

• Te whānui pāmahana me te pāmahana pākū

• Te pāmahana kūtara ki te kāhui, me te paerewa pāmahana ki te pāmahana

• Te kōwhiri i ngā taputapu interface me te ora recohomaru he honohono

• Te ara pūhiko, te kāhui kāhui, me ngā tikanga e.hikari

Ko te hunga i tiaki i ngā pūāhua Kāwai A e maumahara ana ngā hē retihī anō e kore e nui i te mea he kino i te tikanga. Hei tauira, ko te tikanga ki te āwhina i te rārangi oranga pūtea whakarau ka taea e te āhua hiko te pāmua pāmahana i rahi ki te whakawhiti pāmahana. Ka tērā kāwai A e noho ana i te pātea ki ngā pūnaha pāmahana kōhatu i roto i ngā kirioro oro.

Kāwai B

Ko te Class B e whakamahia ana i te nuinga i roto i te whakaritenga pēnā ka whakahaerehia e ia te taputapu mo te hawhe o te waveform. Ka pai ake te efekitā ki te iti o te hiko tuwhera, ā, ka hoki te pānga kāti ki ngā taputapu ka tino heke i te wa kāore he tohu.

Ko te uaua kei te aro ki te raiona pātea. Kāore e tīmata ngā BJTs me ngā MOSFETs ki te whakahaere i runga i te taurangi whakahirahira; me whai hiko/whakawhiti kua oti, ā, ka neke rātou i waenganui. Ka taea e tēnei pūnaha te hanga i tētahi kāwai, i tētahi kātahi rānei i te wā e whakawhiti ana i ngā taputapu, koia pūmau ai te mahi Class B, kāore e whakamahia ana i ngā pūnaha oro tiketike.

I runga i te pire, ka titiro te Class B ki te mea he mea pai i ngā taumata putanga teitei, ā, ka pākere iho ki te pātea e noho ana i te wāhi whakawhiti e whai ana i etahi atu wāhanga nui o te waveform. Ka hoko i tēnei he nui ake te uaua: kāore e whakaatu ngā hopuoro i tētahi rēti pai, ā, ko te pā maunga me te ira pātea ka pērā me te auau. I ngā tikanga pono, ka taea te Class B te tangata pūmau mō tāna efekitā, engari me tango ngā taputapu me ngā hopuoro pātea mō te whakahaere pātea kāore e whāia ā-tikanga.

Ka taea te titiro ki te Kōwae AB hei Kōwae B me tētahi tiakina kāti i hangaia rawa kia mahi tahi enei taputapu i te taha o te pātea. Ka whakaiti tēnei te pānga whakawhiti i te wa e tiakina ana te efekitā ki te mea kei te tata atu te Kōwae B ki te Kōwae A. Mō te nuinga o ngā hua oro, ka riro te Kōwae AB hei "pūtake" e mōhiotia ana nāna i te pai te pātea me te utu me ngā taumata pū.

Ko te mea e wehe i te hoahoa Kōwae AB pai i tētahi mea tau te haere ki te whakahaere pātea i runga i te pāmahana. Ka whakamahia te pātea ki te whakaritenga Vbe e pāngia ana e tētahi kāti tiakina, ā, me whai te pūnaha pātea ki te titiro ki te pāmahana me te tika ki te karo i te pānga hāngū ka pātea te pāmahana. Ko te wahi uaua ko te "titiro ki te pāmahana" ehara i te kaupapa hiko, engari he mea e pā ana ki te whakatakotoranga me te pātea pāmahana.

Ngā taipitopito whakatinana e kitea ana i ngā hanga tūturu ko nga mea e whai ake nei:

• Te whakatakoto i te pūranga pātea e pā ana ki ngā taputapu wera

• Te kounga me te teitei o te pā hei hono ki te pāmahana/whakapae

• Te pāmahana ki te whakauru rerekētanga

• Te haere whakamāhō me te waa pāmahana i te ruma

Ko te tauira papa i te mara he mea ka inihua te whakarewa e paingia ana i te pāmahana, kātahi ka kaha ki te pāti ka nui atu te whakarewa, nāna i te wā e tae ana te ruma ki te koiora pāmahana. Ko ngā hoahoa Kōwae AB e hāngai ana ki te tiaki i te pātea hei raru ki te whakahaere me te noho me te hononga paerewa e taea e ngā punaha hōhonu e noho ana.

Kōwae C

Ka whakahaere te Kōwae C mo te iti iho i te 180° o te huringa. Ko te waveform hiko rēhia he he ko ngā horror he saikona o te pahū pāmahana e lua; e paingia ana he reiti pai mō te mauri oro. I ngā pūnaha RF, kāore tēnei pāti ko te putanga whakamutunga; he pānga tuarua e whakaritea ana e te paerewa.

Ko te pā LC tītohia i te putanga e kōwhiri ana i te auau tūturu e hiahiatia ana e suppressia i ngā pāpā, e tuku ana i te pāmahana kua tukuna ki te auau e hiahiatia ana kia tuwhera mō te pahū pāmahana. Ka whakawhiti te hoahoa i te pātoetoe ki te pāna e pā ana ki te pāmahana kimi takai ki te pānga hoko me te rūma whakatū.

Ko ngā mahi Kōwae C e pā ana ki te RF e haere ana ki ngā rākau e kōwhiri ana:

• Te hoahoa rākau whimsical me te pāpā huringa

• Te pārahi pāmahana me ngā rātau huri

• Te kōwhiri i te Mahi Q, te pāmahana horanga, me te pea raru

• Te pā kei te pāmahana e pā ana ki ngā rākau e hiahiatia ana

I ngā mahi pono, ka mahi te whakarewa me te paerewa hei tahi pūnaha honohono. Ka taea te pātae iti, te rētā rerekētanga, e pā ana ki te efekitā, te putanga hiko, me te pā ki ngā pāmahana. Ko te whakatika i te mahi whakarewa e whakawhirinaki ana ki te paerewa pāmahana e hono ana ki ia.

Kōwae D

Ko te Kōwae D e whakahaere ana i ngā taputapu putanga hei pātea maka, kaua hei waahanga rārangi. Ka whakakākahu te oro mā te PWM, he kōwhiringa e pērā ana ki te rautaki me ngā whakangawari LC. Nā te mea ka noho te rātou i ngā nui katoa, kāore e tawhiti, ka heke te pāpā me ngā hoahoa i te nuinga ka eriş.

Ko te mahi pono i te Kōwae D ko te whakahaere i ngā raru pātea mō te pāhea kāore e hoki ki te pāti oro, e pā ana ki te pāpā e rūkahu ana rātou. Ka whiwhi kaawhi i te pāmahana i ngā hoahoa e whakarite ana, engari ko ngā pānga tuatā pūāhitanga e taea te hanga raru hoahoa uaua.

Ngā tikanga e whakamahia ana hei pupuri i te pātearanga mahi ko ēnei:

• Te pūnaha pani i te pouaka

• Te whakahaere i te wā kāore e pā te pāti me te karo i te pānea kāre e tērā.

• Nga taputapu whakawhiti tere hei whakaiti i te ngako huringa

Ka taea e nga whiringa hangarau taputapu te whakarereke i te waahi hoko. Ko nga taputapu GaN, hei tauira, ka taea te whakaiti i nga ngaronga whakawhiti me te whakapai i te whanonga teitei nui, engari ka mahia hoki e ratou nga kauwhata poauau i te mea ka kaha ake te mana o nga pae i te teitei o te auau.

Ko te nuinga o nga hapa Class D e huri ana ki nga kaupapa whakaritenga tinana e pa ana ki te ahua iti i te wa e noho ana i te kore:

• Te whakauru ki te whenua kei runga i te whakaritenga me te pupuni paera hiko

• Te rōrahi o ngā kāwai tara me ngā ara tuhinga

• Te kōwhiringa snubber me te rautaki damping

• Te pupuni EMI mā te whakaritenga, te kākahu, me te tārua

Ko te mahi a Class D he kōrero mo te whakahaere i nga whanonga RF kaore e hiahiatia ana i te wa e pupuri ana i te rārangi audio pea. Ki te pai te haere, ka taea te rongo i te mau, ki te mea kāore ka noho kāri te kaupapa i nga huarahi e uaua ana ki te tirotiro me nga taputapu puoro anake.

Class T

Ko Class T he mea e taea ana te mārama pai hei rautaki whakahaere e paki ana ki runga i te pātea putanga whakawhiti, kaore he pūtaiao pākiki o te kaupapa hiko. Ko te painga kei runga i te wāhanga whakarereketanga me ngā huarahi pērā i te ao pātea e whakawhānui ana i te pūngao whakawhiti hei whakaiti i ngā tihi EMI kōtuhi. Ahakoa he hītori rongonui te kupu, he maha ngā whakaaro e noho ana kei ngā hoahoa putanga audio pātea iti o nāianei.

I roto i te whakawhanaketanga hua pono, kei te noho e pā ana ēnei rautaki whakahaere ina me tika te pāmu ki te whakamātautau putanga i te wa e noho ana i te ahuru ki ngā korero hihiri, ki nga kōpae iti rānei. Ko te whakahaere tino o nga oro me te whakatutukitanga EMI he nui te whakawhirinaki ki nga mea kotahi, tae atu ki te whanonga whakawhiti pea, nga pānga whakahaere pūmau, me nga pāti hira i roto i ngā wāhanga whakaputa.

Ngā āwangawanga hoahoa e whakaaro ana hei whāinga kotahi i roto i ngā whakaaturanga kaha kei roto:

• Rautaki whakawhāiti me te whakawhāiti ahurei

• Hoahoa urupare me te pūmau āwhā i te huringa / whakaurunga

• Ngā kōwhiringa takawaenga me te kanapa āhuru

• Te whakaaro ki te pātea electromagnetic mai i ngā whakaritenga hoahoa o mua

Ka wātea te benefits heoi i te tikanga Class T-āhua e kua mahia ngā rawa i roto i te whakamahi, karekau he pea e pā ana ki ngā kōtuinga hoko, engari kei runga i te umanga pāti kāore e waihohia mai e ngā whakairo i waenga i ngā kōpae hihiri, ngā ngākaunui, me ngā hanga whakamātau kei te whakahaere.

Nga Pākete Pāmu Hiko

He pāmu hiko e ora ana i waho o te pukapuka karanga ehara i te miihini kotahi e mahi ana i nga mea katoa. Ka hiahia ki te pona e māori ana ki te kōtahi kāwai, a ko ia ake ko ia ka āda i nga rāranga toi e ngaro mai i te kāri i te paetahi ki te pāmu: ka tango te whakakī inoi i te hiiri me nga haweeke, ka mimiti nga tūnga waenga ki te pāma ohorere, ka riro nga tūnga putanga i ngā ngawha pāpāu hiko, ka kī toru ia ki ngā pākete e ngāna kārawaka, me te kaha te ihu e kī kāhore e heke ratou. Ko nga hoahoa e whiwhi ana i te whakawhirinaki mo te wā roa kāore e whakaarohia ēnei pākete hei pūnaha kotahi, nā te mea e pā ana te ohorere ki ngā pānga, ngā taurangi pūmau, ngā whakaritenga tūmau, te kimi āhinga, me ngā āhuatanga pūhiko, ehara i te tautahanga nga utu kōmāmā.

Ko nga whakaritenga o te akomanga AB e tiaki ana i te paerewa kei te mau tonu i te pai ki te pupuri i te kino whakatekau i raro i te paheko tahi. Ko nga poraka whakakaha te pāmahana me te whakatū i te wera ki te hītori a nga taputapu e whakahaerehia ana, he take nui pea ka whakaratohia hei tīwae i te rautaki. Ko te pānui tāpiri i te marae he korerorero e pa ana ki te pīkau i te pāmahana rohe i muri i te whakatū; ko nga tauira e kite ana i te “pai” i runga i ngā haora e pā ana ki te whakahaere i nga huarahi pāmahana hei tikanga hei hanga, kaua e whakaaro ko te āhua whānui anake.

Tiaki: Te Whakamāro i te Hau, Nga Haumaru SOA, me te Whakahoahoa Hātepe

Ka taea e nga tīwae, nga waikawa iti, me nga pūngao reactive te hiki i nga taputapu i waho i to rātou waahi pai ki te whakahaere (SOA). Ka whakatairanga nga whakangahau hei awhina i te whakaiti i te hau, tiaki i te whakaaro SOA, me etahi wa me te mahi whakahoki hei pupuri i te poka i te wa e noho ana te toenga. Ko nga huarahi kōrero e mohio ana te nuinga o nga rōpū ki te mea he kāinga ngā tīwae tiaki e “kāore e tuwhera” i te whakamātautau pea kātahi ka rongo te pai i raro i nga whakaritenga hapa.

He maha nga tauira e pātea ana ki nga whakaritenga teitei i te mea he mea motuhake te pūoro me te rongo hāunga ko te mea e wātea ana i ngā hika pūhiko. Ka whakaatu ngā mahi whārangi hihiko hei whānui mō te āhua i te wā e haere ana te retracting i te wa e pā mai anō ki te wātaka.

Te Pūnaha Kapitani, Te Whakahaere Ripple, me te Hoki ki te Whenua

Ko te whakapiri i te kākano ka whakaiti i te ripple me te tuku i te pūngao i te wāhi, engari ko te āhua tūmau me te āhua hoki e whai ana i te pūngao ki te tote e tango mai ana. Ko nga hautanga hiko nui ka whakahokia mai ki nga huarahi pā whakapiki kahore e whakarato i ngā āhuatanga tūturu e pā ana ki te tepu ka tango ki te tāpiri atu ki te tono. He maha nga raru hiko me nga raru kārangaranga e pā ana ki te rautaki i te tirohanga hiko e tiakina ana i te māngai ka tika i te pūmau kākahu.

Te Tahu Raima, Te Rongoā Rārangi, me ngā Ngā Paru Wera

Ko te tahu raima e pā ana ki te wātea o te wāhi ki te reanga me te taea te neke i te pīhono, i etahi wa e pā ana ki nga raru pāpā auau i ngā pānga. Ko etahi tauira e tango ana i te pehanga paerewa hei momo tāhūhanga ngohengohe, engari ko etahi e rapu ana i o rārangi raru ko te whakautu tūturu. Ko te hiahia ki nga taumata pākahiko e pā ana ki te tautitanga me te awhina e noho ai te raru e taea te tango ki te rapu kaipōti i ngā pānga e auau ana e ahu atu.

Whakahaere, Mātai, me ngā Āhuatanga Tūāpapa Pūkenga

I te whānuitanga o te pū, ka piki ake nga pūnaha me nga tiaki; ka kaha ake ngā rārangi e mahia ana e nāna e tiaki i ngā rōpū hopu, kōkiri i ngā raruraru ma, me te whakaiti i nga raru hemea. Ka awhina hoki i ngā āhuatanga tiaki whakahaere, rānei te puppeteer i roto i te rāhu e pā ana ki te tiaki i ngā tiaki i te pū wā roa.

Tiaki Pouaka

Ko nga taputapu hiko ka whakaheke i te tirohanga mai i ngā hapa DC, te pāmahana kauwhata, me ngā momo tukutubotā. Ko nga whiringa wā, nga āhuatanga pānga (mo nga karere), me nga paerewa tūturu e pā ana ki te护理 e pa ana ki te āhua kāinga i te reais. Ko te nuinga o nga raru o nga rōpū pūoro ka puta mai i nga pāhake, te pūngao, te pārahi huri, kāore rānei ko te mahi whakahī e ngā-rōpū ka pāme tīpono āhua, ko te tiaki hiko he wā e hāngai ana me te pono ka riro hei rawa i te hapa kotahi.

Te Tīpako Pāmahana, Te Whakarite Pāmahana, me te Kaupapa Tūao

Ko nga thermistors, nga sensō pāmahana, me nga kaupapa Vbe-multiplier ka āwhina i te tirotiro i te pāmahana me te whakaiti i te mōrea o te pakū pāmahana. Ko te pāmahana whakakore ka taea te aukati i nga hua kino ka raru te hiki i te hau. He mea nui te ahua o nga sensō e pā ana ki ngā pūrere. Ka taea te whara i ia pāmahana hei pupuri i te pāmahana tapu e whakanui ana i te kūramu e tipu ana.

Nga Boka Motuhake o te Akoranga D

Ka whakauru nga amplifiers Pōtu D i te whanaketanga whakawhiti, nā reira ka timata te hoahoa ki te pooti rorohiko pāhotanga, ahakoa ko te whāinga ko te oro. Ka puta te angitū i konei i te nuinga o te wā mai i te pono mō nga whakaatu hiko i ngā wā e tatari ana, kaua e tatari kia taea e ia te whakatika i muri i te whakamātautau EMI tuatahi.

Te putanga LC Filter me te Interactions Tīraka

Ka whakahou te putanga LC filter i te oro mai i te waveform PWM me whai taiao tonu i roto i te pehanga kaunoa. Ka puta te pānuitanga o ngā wāhanga, ngā āhuatanga whakauru, me te pānga o te taumata mana i ngā taha o te mahi. He pānuitanga mahere ki te hoahoa i ngā whakaritenga kikino me te whakamātautau i ngā taura me ngā kaihoko, nā te mea i runga i te pānga te turuturu me te wiring e mahi ana i runga i te pūnaha paired me tōna ake ake.

Whakahaere EMI: Hoahoa, Tā, Marco, me te Whakatū

He nui te pānga o te whakahaere EMI e te tikanga hoahoa: te whakaiti i te rōrahi, te whakahaere i ngā ara di/dt teitei, me te whakakī i nga wā titi ki te iti ake te kaha. Ko te utunga-whakaingoa, ko te waahanga whakarato teitei, me ngā taputapu whakamahu ka taea te whakamahi, engari kāore e whai pānga i ngā rōrahi nui, he pātea i te haere. He mōhiohio e whakahoki mai ana i ngā tīma e pāhekoheko ana i ngā whakaritenga ki te slag.

He huarahi whai hua ki te āta haere ki te amplifier mana ko te whakahou i te pēnā, te ara hiko, me ngā āhuatanga pāmahana i mua, i mua i te whakakotahi i te kaha ki te rāhuitanga iti. I te wā e noho ana aua āhuatanga, ko te teitei o te rōrahi, ngā whakahoutanga taputapu, me te whakatikatika whakarato ka whakawhiti ki ngā painga e noho ana puta noa i te rōpū rereka me te wiring. Me te kore i taua pūngao, ka taea e nga wāhanga pai te whakaatu i ngā momo hapa hou, ina koa i ngā whakaritenga kaangá me te wiring wahi kāore i te pai, ā, kāore e kitea te putanga e pāremata ana i te wā e tae mai ana ngā pūrongo tīra.

Ngā Ngaāwhina Whakahaere Matua

Ngā Whakatakotoranga Hangarau

Ka ngawari te whakapāhitanga ki ngā whakatakotoranga amplifier i te wā e noho ana ki ngā tikanga whakamātautau e taea te whakahou me ngā pānga ā-tikanga o te hiko. I ahau e pānui ana i te kāhua kōrero, ka harikoa ahau ka ko te mana e tika ana kei te whakahua hei mana tōkeke RMS ki runga i te tiwhikete i whakatauhia, me ngā whakaroa whakamātautau e kore e waiho he wāhi ki te whakamaori. I runga i aua tikanga, ka taea e te ine te kaha, ā, kāore e noho hei whakakatakata ki te whakahaere i roto i te ao.

Ko te pūnaha mana RMS e kitea ana hei te mea tino mārama i te wā e whakaatu ana i te whakaritenga. He tūtohi ka pānui ki ngā pokanga, engari kei te mau pūmau i te wa e rua me te minute ka tūtohu ake ki ngā momo e āta whakarongo ana ngā tangata, ina koa i te wā e pāmahana ana te ruma, ko te puoro he pākiki, me te hui e pākiki ana i te wā hāngai te hei. I te aroha, ka taea e te mana puoro, i ngā whakaritenga poto, te tirohia ki te āhua paku engari ka whakanui i te pānga mo te tuku mana menea kāore e kōkiri i ngā pānga i runga i te pāngarea o te whakaputanga.

Ko ngā tikanga whakamātautau mana RMS e taea te whakarite mō te whakatauhia:

• Ko te pehanga (hei tauira, 8 Ω, 4 Ω)

• Ko te rahi (hei tauira, 20 Hz–20 kHz)

• Te āheinga tūkino i te whāingatū (hei tauira, 0.1% THD)

• Te tikanga mana o te rārangi (hei tauira, e rua ngā rārangi e kūmau ana mō ngā rōpū stereo)

Ko te tākai hātepe mōhihi (THD) he taputapu kikino, engari ko te mea hoki ka tukuna he mōhiohio e pā ana ki te tirotiroha. Ko ngā pānga THD i te 1 kHz ka pāngia e te mana pupuni e te pūmau i te pūmau, engari ka kitea e au te kawe i te THD e heke ana i ngā rahi, ko te taumata whakaputanga e tae ana ki te taumata, me te hātepe e kore e noho ki te pai. Ko aua huri ka mau mai ki te hātepe o te amplifier, kāore hei reo hokohoko, engari hei pānui mōhiohiko e taea ana te matohi.

Ngā take noa e piki ana i te THD i ngā ine tūturu:

• Te pikinga i ngā rūnanga THD ki te taputapu e whakaaro ana ki te rahi rōrahi o te hūri

• Ngā whiringa tuku e pānga ana ki te tere ki te tautokohia

• Te rahi whakaputanga kore-whakauru e te tukua ki te wātea o te pēhanga

• Ngā whakaāio tākārua e kīa ana e ngā āhuatanga teitei, ka taea te tuhituhi i ngā hūpe kehe

Ko te reiti rahi e huna ana ki te pā pito i te tere e rahi ake te mana e taea ana te huri, ā, ko te pito ka kitea e te pānui i runga i ngā wā poto. I te wā e pātea mai ana te reiti rahi, kāore e waiho he pāti.

Ngā whakaaturanga hoahoa e pā ana ki te hīko rahi e huaina ana:

• Te pānga hiko o tōna wāhanga tauhiuhia

• Ngā uara o ngā kākā pūwhakataka

• Te mārama waikore e te kaihoko me ngā taura

He huarahi whaihua ki te whakaaro mo tenei ko te tirotiro i te ahua e whanakehia ana te whakakōrero ki nga hurihanga koi, teitei-nui ki roto i te kaihanga uaua. Ko nga wahanga e whai ana i te rahi tika e mau tonu ana te korero me te kore e pakaru, na te mea kaore e kaha ki te whakaora.

Ko te whakatūpato tikanga e pā ana ki te hiko whakauru me te mea nui i nga taumahanga kōkiri me te huihui back-EMF. Ka taea te whakapai ake i te whakahaere pātea, engari ko te whakatūpato tikanga i nga tumu kōtaha e pā ana hoki ki ngā taura, ngā hononga, me ētahi atu tino pānga ā-waho. Na reira, ko nga whakatūpato tikanga tino tiketike, kāore pea e taea te whakaatu i nga whakaritenga mahi tūturu.

Nga whakatūpato pūnaha e mohiotia ana hei pahū i te rahi tūturu i te kaiwhakahaere:

• Te pāmahana taura kāmera

• Nga ngaronga hononga/ngā pā

• Ko nga inductors whakawhiti me nga wāhanga rārangi

• Ko te raru pā koutou i te wa

Na, hei whakakī i te whakatūpato tikanga hei taupānga whakakeke, e pā ana pea ki te mau pona pātea me te tauwhitianga kā nga pātea, nga hononga, me te noho e kitea ana hei pūnaha kāinga noa iho, kāore he whakaritenga whakahaere.

Ko te āheinga pāmahana ko te mea e kīia ana hei whakamātautau pākawe mea kaha nāna i akiaki te whakaheke i nga tīwae. Ko te mahi ki te 4 Ω me te 2 Ω tārua, me ngā tārua whakahaere ki ngā raru pahū me ngā kokonga taumaha, e pā ana ki te whakahaere i ngā taputapu whakauru, ko te rārangi i te pico, ko te aroturukihanga pātea e pā ana ki te mau pū. Ko te āhuatanga matua, kāore e kore, ko te mea kāore te whakakōrero e mahi, engari ko te tiakina te mahi me te rārangi i noshi e noho ki nga tapawha noho ka noho tonu, kāore he panoni, he pānga, he whakaroa pā te pā i te kounga o te oro.

Nga pūnaha kaimatū e whakatau ana i te pānga raro-nui:

• Ko te whiriwhiri taputapu whakauru me te whakahaere i nga wāhi e haumaru ana

• Te rautaki whakaritenga pāmahana (kei te anga ana me te peha tonu)

• Ko te pātea pēnā e pā ana ki te kuku e mau ana

• Te aroturuki pātea me te whai huarahi pā e kaha ana

I te whakamahinga tūturu, kua kite au i te tauira: ko te whakahau me ngā whakatūpato whakahāwehe ka pā te hiahia ki te painga ki te mau pā, katahi ka raru i te pūkete rahi i te hīnaki kāore i ngā kii me te pānga i te tōpū rahi. Ko nga whakawhitinga e kākahu ana i te pātea me te aroturuki kaha he pānui pea ki rārangi pea o ngā pā, e kore e noho rīriki engari e noho ana te kawe i te ratarata o ngā kangakanga.

Nga Āhuatanga Whakaari

Ko te taurite ka noho ki ngā waewae e noho ana i te paearu me te waehere e mapuia ana ki ngā whakaritenga whakaronga e taea te tango i te hāngai. Kua ako au ki te noho pūmau ki ngā tau kotahi e pa ana; ka taea te whakatutuki i te 'emocional satisfaction’, he māmā, he ngawari, he whakakāhaki, ā, kāore e taea te whakaatu me pēhea e riro ai te whakakōrero ki ngā kai makau i ngā kaipūhā tūturu.

Ka whai pūmau te pūngao i te mahinga pai hei wahanga kura nāna i whakaatu i te kaha mojium. Ko nga whakatūpato pā kāore i te pīhai e pā ana ko te pakengati pea nga pā, ina kimi te rārangi hūhuru e raru ana i te kāinga ka raru ranei i te whakarani. Ki te haumaru i te pūngao ki ngā pūnaha kai, ko te pātai whaihua ko te mea ka taea e te rohe me te utu katoa te tuku hāngai ki te waehere mō te whakaora i te kāinga noho kāore i te whakamau i ngā pā.

Nga rreason e pā ana ki ngā rangi “tika-hīhiri” e kāore i te mahi i te wā e arahi ana:

• Te pūngao e whanakehia ana mo ngā kōwhiringa poto, kāore i te e rho

• Te pā kākahu e whakarārangi ana mo te rata kāore i te hui tūturu

• Ko te whakanui i te whakaora kaore e akina i raro i te pāngawai eha

Ko te whakawhiti pāna ki runga i te ako e rewa ana i te kiko ki te pōtuī. Ka tino whakamahi ka nui ki te whakawehe pā e pā ana ki te pā me ngā whanaunga pā, ka whakapau i te wā hangore e mohiotia ana i te kāinga e pā ana ki te whakapakari ki te wāhanga. Ko taau e rapu ana ehara i te pāmoa te pāhua, engari ko te pākonikoni i raro i te pā, nāna i tupu mai i ēnei te āhua he whakaata i te pā mi ētahi poupou.

Nga āhuatanga e wehe ana e pa ana ki te kōwhiringa pāna tere e pa ana ki rārangi nui tetahi ka raru:

• Ko te ripa pūna e hanga ki te te Tangata me te mahi

• Ko te pāpā o te rerenga e ārai ana nāna i te timatanga e pehi ana

• Te whānui pēna e ārai ana i nga raki whai i te rahi tuari.

Ko te Ratio rōrahi ki te pāpāho (SNR) e whakaatu ana i te pātea o te whakakaha i te pānga ki te putanga i te katoa, engari ka riro te raupapa hei tikanga anake ina kua kōwhiria te kātara me te taumata tohu. Ka pā ki te 100 dB i ngā hua tūturu, me tohu te pātea teitei i mua atu; e tohu ana i te hangarau alitanga сурū tūhononga, ngā rēmana ma, te hihiri whānui, me ngā kōwhiringa kōtuinga e māmā ake te pāpāho me te pupuri i te riri pāpāho i te pokanga hihiri. I konei ka kitea e au te āwangawanga: kāore pea e whakaaturia ana e te tohu te kounga, ā, kāore pea e puāwai te pūnaha kua whakauruhia ki te hihiri me te āhukahuka.

Ngā āhuatanga hoahoa me te whakakotahi e tino pā ana ki te riri o te ao tūturu:
