Ulwazi olubandayo oluvakalayo: ukuhambelana nokugcinwa kwamandla

I-1.Isithethi: ukwenzela ukujamelana nempembelelo ye-pulse eqinile ngokukhawuleza kwisignali yeprogram ngaphandle komonakalo okanye ukuphazamiseka.Nali ixabiso lovavanyo ekubhekiselelwe kulo: amandla alinganiselweyo esithethi esikhethiweyo kufuneka aphindwe kathathu kubalo lwethiyori.
I-2.I-amplifier yamandla: xa kuthelekiswa ne-transistor amplifier yamandla, ukugcinwa kwamandla afunekayo kuyahluka.Oku kungenxa yokuba igophe eligqithileyo le-tube amplifier ligudile.Kwincopho yophawu lomculo olugcwele kakhulu, iamplifier ityhubhu ayivelisi isenzeko sokusika amaza, kodwa yenza incam yencopho ibe yingqukuva.Le yinto esihlala siyibiza ngokuba ziincopho zokucheba eziguquguqukayo.Emva kweamplifier yamandla e-transistor kwindawo yokulayisha ngaphezulu, ukugqwetheka okungahambelaniyo kuyanda ngokukhawuleza, okuvelisa ukusika kwamaza okunzulu kumqondiso.Ayiyenzi incopho ibengqukuva, kodwa iyicoca kakuhle.Abanye abantu basebenzisa i-impedance edibeneyo yokumelana, i-inductance kunye ne-capacitance ukulinganisa isandisi-lizwi, kunye nokuvavanya amandla okwenene emveliso yeentlobo ezininzi zomgangatho ophezulu we-transistor amplifiers.Iziphumo zibonisa ukuba xa umthwalo unenguqu yesigaba, kukho i-amplifier yamandla ebizwa ngokuba yi-100W, kwaye amandla okuvelisa ngokwenene yi-5W kuphela xa ukuphazamiseka ku-1%!Ke, ukhetho lwesixa esigciniweyo se-transistor amandla amplifier:
I-amplifier yokuthembeka okuphezulu: amaxesha angama-10
Iamplifier yamandla ekwibakala eliphezulu: amaxesha ama-6
I-amplifier yamandla aphakathi koluntu: amaxesha ama-3 amaxesha ama-4
I-amplifier yamandla ityhubhu ingaba yincinci kakhulu kunomlinganiselo ongentla.
3.Ungakanani umjikelo omele ushiywe kumyinge wenqanaba loxinzelelo lwesandi kunye nowona mgangatho woxinzelelo lwesandi uphezulu kwisixokelelwano.Kufuneka ixhomekeke kumxholo kunye nendawo yokusebenza yenkqubo yosasazo.Le 10dB incinci engafunekiyo, kumculo wepop wangoku, ukutsiba bungee kunye nomnye umculo, kufuneka ishiye i-20 ~ 25dB yokuphindaphinda, ukuze inkqubo yomsindo.Sebenza ngokukhuselekileyo nangokuzinzileyo.
