Isakhiwo esiyisisekelo sesilawuli kude somnyango wegaraji

Ingxenye yokudlulisa yeiremote yomnyango wegarajingokuvamile ihlukaniswe yaba izinhlobo ezimbili, okungukuthi, isilawuli kude(Irimothi yomnyango wegaraji)kanye nemojula yokudlulisa. Isilawuli esikude kanye nemojuli yesilawuli kude ezemodi yokusetshenziswa. Isilawuli esikude singasetshenziswa ngokuzimela njengomshini ophelele, futhi umugqa ophumayo wangaphandle unekhanda lenqwaba yezintambo; Imojula yesilawuli kude isetshenziswa njengengxenye kusekethe futhi isetshenziswa ngokuya ngencazelo yephinikhodi yayo. Inzuzo yokusebenzisa imodyuli yesilawuli kude yukuthi ingaxhunywa ngaphandle komthungo nesifunda sohlelo lokusebenza, ivolumu encane, intengo ephansi futhi isebenzise kahle yonke into. Kodwa-ke, umsebenzisi kufanele aqonde ngempela isimiso sesifunda. Uma kungenjalo, kulula ukusebenzisa isilawuli kude.

Ngokuvamile, ingxenye eyamukelayo yeiremote yomnyango wegarajinayo ihlukaniswe yaba izinhlobo ezimbili, okuyilezisuper heterodyne egalaji umnyango okudekanye nemodi yokwamukela evuselelayo kakhuluIsilawuli kude somnyango wegaraji. I-super regenerative demodulation circuit ibizwa nangokuthi i-super regenerative discovery circuit. Eqinisweni, isifunda sokuthola kabusha esisebenza kusimo se-oscillation esiphakathi. I-Superheterodyne demodulation circuit iyafana nomsakazo we-superheterodyne. Ifakwe isekethe ye-oscillation yendawo ukuze ikhiqize isignali ye-oscillation. Ngemva kokuxuba nesignali yefrikhwensi yenkampani yenethiwekhi etholiwe, imvamisa emaphakathi (ngokuvamile engu-465kHZ) iyatholakala. Ngemva kokukhulisa imvamisa yamaphakathi nokutholwa, isignali yedatha iyehliswa. Ngenxa yokuthi ifrikhwensi yenkampani yenethiwekhi ilungisiwe, ukujikeleza kwayo kulula kunomsakazo. Umamukeli we-superheterodyne unezinzuzo zokuzinza, ukuzwela okuphezulu kanye nekhono elihle lokulwa nokuphazamiseka; Isamukeli sokuvuselela kabusha sincane futhi sishibhile. Kulula ukuxazulula.
