Uhlolojikelele
Isithiyo sokuphepha esihlukanisiwe esinomsebenzi wokuvikela ukukhuphuka kokuphuma kwe-switch transistor, ehlukanisa futhi idlulisele amasiginali okokufaka ukusuka kothintana nabo abashintshayo noma amaswishi aseduze ezindaweni eziyingozi ukuya endaweni yokuphepha ene-transistor ephumayo ngokusebenzisa umgoqo wokuphepha. Ukutholwa kwephutha lomugqa kutholwa nge-LED ngaphezulu kwemojuli. Ukushintsha kokudayela kwemojuli isetshenziselwa ukusetha okokufaka nokukhiphayo esigabeni noma ukulawula okuhlehlayo, kanye nokunika amandla noma ukukhubaza umsebenzi wenkomba ye-alamu yokuthola iphutha.
Lo mkhiqizo udinga ukunikezwa kwamandla okuzimele, okunokunikezwa kwamandla okukodwa, okokufaka, namatheminali aphumayo.
