Khayraadka Dheeraadka ah

Amplifier-ku waa aalad kor u qaada tamarta ama awoodda signalka wax soo gelinta.Waxay ka kooban tahay tubbada elektarooniga ah ama transistor, koronto beddele, iyo qaybo kale oo koronto ah.Loo isticmaalo isgaarsiinta, baahinta, radar, telefishinka, kantaroolka tooska ah iyo aaladaha kale.

Aalad kordhisa baaxadda ama awoodda signalka.Waa qayb muhiim ah oo ka mid ah habaynta calaamadaha qalabka otomaatiga ah.Shaqada weyneynta ee cod-weyneeye waxaa lagu gartaa calaamadda gelinta si loo xakameeyo tamarta, iyo isticmaalka awoodda loo baahan yahay in lagu kordhiyo waxaa bixiya tamarta.Cod-weyneyaasha toosan, wax-soo-saarku waa ku-noqnoqoshada iyo kor-u-qaadista calaamadda gelinta.Cod-weyneyaasha aan tooska ahayn, wax-soo-saarku waa shaqo ka mid ah calaamadaha wax-gelinta.Marka loo eego tirada jireed ee cod-weyneeye farsamaynta calaamadaha waxa loo qaybiyaa cod-weyneeye farsamaysan, cod-weyneeye elektirooni ah, cod-weyneeye elektaroonig ah, cod-weyneeye hawo-qaade iyo cod-weyneeye oof-wareen, kuwaas oo inta badan la isticmaalo waa cod-weyneeye elektaroonig ah.Faafinta tignoolajiyada efflux-ka (fiiri element efflux), cod-weyneyaasha hawo-qaadeyaasha ama pneumatic-ka ayaa si tartiib tartiib ah u kordhay.Cod-weyneyaasha elektarooniga ah waxaa loo qaybiyaa cod-weyneyaasha tuubbada vacuum, amplifiers transistor, amplifiers adag iyo amplifiers magnet-ka iyadoo loo eegayo aaladaha firfircoon ee la isticmaalo, kuwaas oo cod-weyneyaasha transistor ay yihiin kuwa ugu isticmaalka badan.Cod-weyneyaasha Transistor-ka waxaa inta badan loo adeegsadaa kor-u-qaadista danabka iyo kor-u-qaadista calaamadaha hadda ee aaladaha otomaatiga ah, badi ahaan qaab-weyneyn hal-dhammad ah iyo kor-u-qaadista riix-jiid.

Mabda'a: Cod-weyneeye koronto badan oo soo noqnoqonaya ayaa la isticmaalaa marxaladda ugu dambeysa ee gudbiyaha.Shaqadiisu waa in ay xoojiso awoodda signalka hirarka modulated ee inta jeer ee sarreeya si ay u buuxiso shuruudaha awoodda dirida, ka dibna u soo ifbixisa meel bannaan iyada oo loo marayo anteenada si loo hubiyo in soo-dhoweeyaha meel gaar ah uu heli karo heerka signalka lagu qanco, mana uusan helin. farageliyaan isgaarsiinta kanaalada ku xiga.

Cod-weyneeye awoodda soo noqnoqda ee sarreeya waa qayb muhiim ah oo ka mid ah qalabka gudbinta ee nidaamka isgaarsiinta.Marka loo eego ballaca guusheeda soo noqnoqoshada shaqadeeda, waxa loo qaybin karaa cod-weyneeye koronto-sare oo cidhiidhi ah iyo band-ballaaran.Cod-weyneeye koronto-sare oo cidhiidhi ah wuxuu caadi ahaan qaataa wareegga xulashada soo noqnoqda oo leh shaqada shaandhaynta xulashada soo noqnoqda sida wareegga wax soo saarka, sidaas darteed waxaa sidoo kale loo yaqaannaa cod-weyneeye koronto oo tuned ama cod-weyneeye koronto.Wareegga wax soo saarka ee cod-weyneeye koronto-sare oo ballaaran waa koronto-bixiye xariiqda gudbinta ama wareegga kale ee is-barbar-dhigga ballaaran, sidaas darteed waxaa sidoo kale loo yaqaannaa cod-weyneeye koronto aan la toosin.Cod-weyneeye koronto-sare waa nooc ka mid ah aaladaha beddelka tamarta, kaas oo u beddela tamarta DC ee ay bixiso korontadu una beddelo soo-saarka soo noqnoqoshada sare ee AC.Waxaa la og yahay in koorsada "Low soo noqnoqda Elektaroonigga ah".Marka loo eego xagasha wax-qabadka ee kala duwan, cod-weyneeye waxa loo qaybin karaa A, B, C saddex nooc oo ah gobolo shaqo.Xagalka socodka hadda ee cod-weyneeye Heerka A waa 360o, kaas oo ku habboon calaamad yar iyo kor u qaadida awoodda hoose.Xagalka socodka hadda ee cod-weyneeye heerka B wuxuu ku saabsan yahay 180o;Heerka C cod-weyneeye socodka qulqulka hadda wuxuu ka yar yahay 180o.Fasalka B iyo C labaduba waxay ku habboon yihiin shaqada awoodda sare leh.Awoodda wax-soo-saarka iyo hufnaanta xaaladda shaqada ee heerka C waa tan ugu sarreysa saddexda xaaladood ee shaqada.Cod-weyneyaasha awoodda soo noqnoqda ee inta badan waxay ku shaqeeyaan fasalka C. Si kastaba ha ahaatee, qalloocinta qaab-dhismeedka hadda jira ee cod-weyneyaasha Class C waa mid aad u weyn oo loo isticmaali karo kor-u-qaadista awoodda-soo noqnoqda ee hooseeya, waxaana loo isticmaali karaa oo keliya koronto-weyneysiinta iyada oo loop-gaaban sida raran.Sababtoo ah awoodda shaandhaynta ee wareegga toosan, wareegga wareegga iyo korantada ayaa weli aad ugu dhow mawjada sinusoidal iyo qalloocintu aad bay u yar tahay.
