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 kwe-transistor amplifier yamandla kwindawo yokulayisha ngaphezulu, ukugqwetheka okungaqhelekanga kuyanda ngokukhawuleza, nto leyo evelisa ukusika okukhulu kwamaza 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 okwenene aphumayo yi-5W kuphela xa ukuphazamiseka ku-1%!Ke, ukhetho lwesixa esigciniweyo se-transistor amandla amplifier:
I-amplifier yokuthembeka okuphezulu: amaxesha angama-10
Iamplifier yamandla ekwinqanaba eliphezulu: amaxesha ama-6
I-amplifier yamandla ephakathi: amaxesha ama-3 amaxesha ama-4
I-amplifier yamandla ityhubhu ingaba ncinane kakhulu kunomlinganiselo ongentla.
3.Ungakanani umda omele ushiywe kumyinge woxinzelelo lwesandi kunye nowona mgangatho woxinzelelo lwesandi uphezulu kwisixokelelwano.Kufuneka ixhomekeke kumxholo kunye nendawo yokusebenza yenkqubo yosasazo.Le 10dB incinci engafunekiyo, kumculo wepop wanamhlanje, ukutsiba bungee kunye nomnye umculo, kufuneka ishiye i-20 ~ 25dB yokuphindaphinda, ukuze inkqubo yomsindo.Sebenza ngokukhuselekileyo nangokuzinzileyo.
