Mapangidwe oyambira a khomo la garaja kutali

Kupatsirana gawo lambali ya chitseko cha garagenthawi zambiri amagawidwa m'mitundu iwiri, yomwe ndi yowongolera kutali(Remote ya chitseko cha garage)ndi module yotumizira. Woyang'anira kutali ndi gawo loyang'anira kutali ndizogwiritsa ntchito. Woyang'anira kutali angagwiritsidwe ntchito paokha ngati makina athunthu, ndipo mzere wotuluka kunja uli ndi mutu wa mulu wa waya; Module yoyendetsera kutali imagwiritsidwa ntchito ngati gawo lozungulira ndipo imagwiritsidwa ntchito molingana ndi tanthauzo lake la pini. Ubwino wogwiritsa ntchito gawo lakutali ndikuti ukhoza kulumikizidwa mosasunthika ndi dera logwiritsira ntchito, voliyumu yaying'ono, mtengo wotsika komanso kugwiritsa ntchito bwino chilichonse. Komabe, wogwiritsa ntchitoyo ayenera kumvetsetsa mfundo yozungulira. Apo ayi, ndi bwino kugwiritsa ntchito remote control.

Nthawi zambiri, gawo lolandira lambali ya chitseko cha garagewagawidwanso mitundu iwiri, yomwe ndisuper heterodyne garage chitseko chakutalindi wapamwamba regenerative kulandira modekhomo la garaja kutali. Super regenerative demodulation circuit imatchedwanso super regenerative discovery circuit. M'malo mwake, ndi gawo lodziwikiratu lomwe limagwira ntchito munthawi ya oscillation. Superheterodyne demodulation circuit ndi yofanana ndi wailesi ya superheterodyne. Ili ndi ma oscillation ozungulira kuti apange chizindikiro cha oscillation. Pambuyo posakanikirana ndi chizindikiro chafupipafupi chonyamulira chonyamulira, chizindikiro chapakati (nthawi zambiri 465kHZ) chimapezeka. Pambuyo pakukulitsa kwapakatikati ndikuzindikira, chizindikiro cha data chimasinthidwa. Chifukwa ma frequency onyamula amakhazikika, kuzungulira kwake kumakhala kosavuta kuposa wailesi. Wolandira superheterodyne ali ndi ubwino wokhazikika, kukhudzika kwakukulu komanso mphamvu zabwino zotsutsana ndi kusokoneza; Super regenerative receiver ndi yaying'ono komanso yotsika mtengo. Zosavuta kuthetsa.
