A cikin kayan lantarki, haɗin fasaha na fasaha da ingantaccen ƙira yana da mahimmanci.Masu ba da gudummawa guda biyu masu mahimmanci ga wannan filin sune pulse code modulation (PCM) da bugu na allon kewayawa (PCB).PCM da PCB ana amfani da su sosai a cikin na'urorin lantarki daban-daban, kuma kowanne yana da nasa fa'idodi da halaye.A cikin wannan shafi, za mu rarraba bambance-bambance da iyawar PCMs da PCBs don sanin wane zaɓi ya fi dacewa da bukatunku.
PCM (Modulation Code Modulation):
Modulation na lamba bugun jini hanya ce ta dijital don wakiltar siginar analog.Yana jujjuya siginar analog zuwa nau'i na dijital kuma ana amfani dashi galibi a aikace-aikacen sauti kamar rikodi da samar da kiɗa.PCM lokaci-lokaci yana ɗaukar girman kowane samfurin siginar analog kuma yana wakiltar shi a lambobi.Wannan dabarar samfurin tana sake haifar da siginar analog na asali daidai.PCM yana ba da ingantaccen sauti mai kyau kuma an san shi don babban amincinsa, yana mai da shi manufa don tsara tsarin sauti da kayan aiki waɗanda ke buƙatar ingancin sauti mara kyau.
PCB (Printed Circuit Board):
Buga allon kewayawa sune tushen zahiri na na'urorin lantarki, suna samar da dandamali don haɗin kai na sassa daban-daban.PCB yana kunshe da hanyoyin tafiyarwa da aka tsara a cikin wani abu mara amfani don samar da haɗin lantarki da tallafin injina don abubuwan da aka gyara.PCBs suna sauƙaƙe tsari da haɗin kai na kayan lantarki daban-daban kamar resistors, capacitors da microchips.Sassauci na ƙirar PCB yana ba da damar haɗaɗɗun shirye-shiryen da'ira, yana mai da shi yin amfani da shi sosai a masana'antu daban-daban kamar sadarwa, sararin samaniya, da na'urorin lantarki.
Abubuwan banbance-banbance:
1. Aiki:
PCM galibi yana mai da hankali kan sarrafa siginar sauti na dijital don samar da ingantaccen sauti mai inganci.A gefe guda kuma, PCBs suna ba da gudummawa ga aikin gabaɗaya na na'urorin lantarki, sauƙaƙe haɗin haɗin sassa daban-daban da samar da kwanciyar hankali ga tsarin.Yayin da PCMs wani bangare ne na tsarin sauti, ana amfani da PCB a kusan kowace na'urar lantarki, daga wayoyin hannu zuwa kayan aikin likita.
2. Rubutun ƙira:
PCM ya ƙunshi algorithms na software da ci-gaba da dabarun sarrafa sigina.Duk da yake yana buƙatar ƙwarewa a cikin injiniyan sauti da ƙwarewar shirye-shirye don haɓaka aikin sa, yana da sauƙi a cikin yanayin ƙirar jiki.Sabanin haka, ƙirar PCB na buƙatar tsara shimfidar wuri a hankali, sanya sassa, da nazarin haɗin lantarki.Yana buƙatar ilimin injiniyan lantarki da ingantattun ayyukan ƙira don cimma aikin da ake so.
3. Yawanci:
An ƙera PCM musamman don aikace-aikacen sauti don tabbatar da ingantaccen sauti da kuma rage murdiya.Babban burinsa shine kiyaye mutuncin siginar sauti a cikin yankin dijital.A gefe guda, PCBs ba su iyakance ga kowane takamaiman aikace-aikace ko masana'antu ba.Ƙwaƙwalwarsu tana ba su damar ƙera su don biyan buƙatun kowace na'ura na lantarki, walau na'urar kiɗa mai ɗaukar hoto ko tsarin sadarwar tauraron dan adam.
a ƙarshe:
Dukansu PCMs da PCBs sune masu ba da gudummawa mai mahimmanci ga fannin lantarki, kowanne yana yin manufa ta musamman.PCM shine zaɓi na farko na injiniyoyin sauti da audiophiles don ingantaccen ingancin sauti.PCBs sune tushen da aka gina hadaddun tsarin lantarki akansa, yana tabbatar da haɗin kai da kwanciyar hankali.Kodayake PCMs da PCBs sun bambanta a aiki da ƙira, galibi ana amfani da su tare a cikin na'urorin lantarki, suna haɗa ƙarfinsu na musamman.
A ƙarshe, ya zo ne ga takamaiman buƙatun aikinku ko kayan aikin ku.Fahimtar bambance-bambance da halayen PCMs da PCBs zai ba ku damar yanke shawara mai fa'ida dangane da bukatunku.Don haka ko kuna gina tsarin hi-fi ko ƙirƙirar kayan aikin lantarki da yawa, PCMs da PCBs kayan aiki ne masu mahimmanci don haɓaka fasaha.
