Iplagi yokuva ioyile ibhekisa kwisenzi soxinzelelo lweoyile. Umgaqo kukuba xa injini isebenza, isixhobo sokulinganisa uxinzelelo sibona uxinzelelo lweoyile, siguqule isignali yoxinzelelo ibe sisignali yombane, size siyithumele kwisekethe yokucubungula isignali. Emva kokwandiswa kwevolthi kunye nokwandiswa kwamandla ombane, isignali yoxinzelelo olunyusiweyo iqhagamshelwe negeyiji yoxinzelelo lweoyile ngomgca wesignali.
Uxinzelelo lweoyile yenjini luboniswa ngumlinganiselo wamandla ombane phakathi kweekhoyili ezimbini kwisalathisi soxinzelelo lweoyile eguquguqukayo. Emva kokwandiswa kwevolthi kunye nokwandiswa kwamandla ombane, isignali yoxinzelelo ithelekiswa nevolthi yealamu esetiweyo kwisekethe yealamu. Xa ivolthi yealamu iphantsi kunevolthi yealamu, isekethe yealamu ikhupha isignali yealamu kwaye ikhanyise isibane sealamu ngomgca wealamu.
Isixhobo sokuvavanya uxinzelelo lweoyile sisixhobo esibalulekileyo sokufumanisa uxinzelelo lweoyile yenjini yemoto. Ukulinganisa kunceda ukulawula ukusebenza kwenjini okuqhelekileyo.
Iplagi yokuva ioyile yenziwe ngetshiphu yesivamvo soxinzelelo lwefilimu etyebileyo, isekethe yokucubungula isignali, i-housing, isixhobo sebhodi yesekethe esisigxina kunye neentambo ezimbini (umgca wesignali kunye nomgca we-alamu). Isekethe yokucubungula isignali inesekethe yombane, isekethe yokuhlawula isivamvo, isekethe yokubeka i-zero, isekethe yokukhulisa i-voltage, isekethe yokukhulisa i-current, isekethe yesihluzo kunye nesekethe ye-alamu.
