Yintoni isekethe yeamplifier yamandla?
Ngaphambi kokuba sihlolisise iimpawu zabo, masiqale sichaze ukuba sithetha ntoni ngesekethe yeamplifier yamandla.Ukubeka nje, isiphaluka se-amplifier yamandla yisekethe ye-electronic ekhulisa izibonakaliso zombane ukuya kwinqanaba eliphezulu lamandla elifanelekileyo lokuqhuba umthwalo, njengesithethi okanye i-antenna.Ngokwesiqhelo, iisekethe zeamplifier zamandla zithatha isandi esisezantsi okanye isiginali yokufakwa kwamaza kanomathotholo kwaye iyandise kakhulu ukunika amandla ayimfuneko kwisicelo esicetywayo.
Iimpawu zesekethe yeamplifier yamandla
1. Amandla okuphatha amandla: Iisekethe ze-amplifier zamandla zenzelwe ukuphatha amanqanaba aphezulu ombane xa kuthelekiswa nezinye iintlobo ze-amplifiers.Ukukwazi kwabo ukuhambisa amandla abalulekileyo kubenza bakwazi ukuqhuba imithwalo efunekayo ngokufanelekileyo nangokuthembeka.
2. Umgca: I-amplifiers yamandla izama ukugcina ngokuchanekileyo imilo kunye neenkcukacha zesignali yegalelo.Umgca ubalulekile ekunciphiseni ukugqwetheka kunye nokuqinisekisa ukuveliswa okuthembekileyo komqondiso wokuqala.
3. Ucikizeko: Ucikizeko yingqwalasela ephambili kwiisekethe zeamplifier yamandla kuba imisela ukuguqulwa kwamandla ombane kumandla aluncedo aphumayo.Izandisi zamandla ezikumgangatho ophezulu zinciphisa inkcitho yamandla, ngaloo ndlela zinciphisa ukusetyenziswa kwebhetri kunye nokutshatyalaliswa kobushushu.
4. I-Bandwidth: I-bandwidth yesekethe ye-amplifier yamandla ibhekisela kuluhlu lwamafrikhwensi olunokuthi lukhulise ngokuthembekileyo.Ngokuxhomekeke kwisicelo, ii-amplifiers zamandla zinokuhlelwa njenge-audio amplifiers ezisebenza kuluhlu lwe-audio, okanye i-audio frequency amplifiers esetyenziswa kwiinkqubo zonxibelelwano ezingenazintambo.
Imisebenzi ephambili yesekethe yeamplifier yamandla
1. Ukwandiswa komqondiso: Umsebenzi oyintloko wesiphaluka se-amplifier yamandla kukukhulisa isignali kwinqanaba eliphezulu lamandla ukuze likwazi ukunqoba ukuxhatshazwa komthwalo, njengesithethi okanye i-antenna.I-amplifiers yamandla igcina ukuthembeka kunye nomgangatho wesignali yegalelo ngelixa inika amandla aneleyo okuqhuba umthwalo.
2. I-impedance ehambelanayo: Iisekethe ze-amplifier zamandla zihlala zixhotyiswe nge-impedance ehambelana nenethiwekhi ukuze kuphuculwe ukuhanjiswa kwamandla phakathi kwe-amplifier kunye nomthwalo.Oku kuqinisekisa ukuba amandla aphezulu ahanjiswa, ukunciphisa ukubonakaliswa kunye nokulahleka komqondiso.
3. Ubume boMqondiso: I-amplifiers yamandla inokuqulatha izigaba zokumisa umqondiso wokuphucula umgangatho wesignali yegalelo, ukususa ingxolo, okanye ukusebenzisa isihluzo esithile ukulungelelanisa imveliso yesicelo esithile.Ezi zigaba zinokubandakanya ii-preamplifiers, izilinganisi, okanye izihluzi.
4. Iisekethe zokukhusela: Iisekethe ze-amplifier zamandla zihlala zinezijikelezo zokukhusela ezakhelwe ngaphakathi ukukhusela umonakalo onokuthi ubangelwa ngumbane ogqithiseleyo, okwangoku, okanye ubushushu.Ezi ndlela zokukhusela zinceda ukwandisa ubomi be-amplifier ngelixa uqinisekisa ukusebenza ngokukhuselekileyo.
Ukuqukumbela
Ukushwankathela, iisekethe zeamplifier zamandla zizinto eziyimfuneko kwiintlobo ngeentlobo zeaudio kunye nosetyenziso lweRF.Iimpawu zabo, ezifana nokuphatha amandla, umgca, ukusebenza kakuhle, kunye ne-bandwidth, ichaza amandla abo okusebenza.Ukuqonda imisebenzi ephambili ye-amplifiers yamandla, kubandakanywa ukukhulisa umqondiso, ukulinganisa i-impedance, ukulungiswa kweempawu kunye nokukhuselwa, kusivumela ukuba siqonde ukubaluleka kwabo ekuqhubeni izithethi, ukuhambisa iimpawu kunye nokubonelela ngamava omsindo ophezulu.Njengoko itekhnoloji ihambela phambili, ii-amplifiers ziyaqhubeka nokuvela ukuze zibonelele ngokusebenza okuphezulu, ukusebenza kakuhle, kunye nokuguquguquka kwezinto ezininzi ze-elektroniki.
