In a superheterodyne receiver, a response caused by a signal that enters the receiver on a frequency that differs from the local oscillator frequency by the amount of the IF. The signal, however, is on the side opposite the normal response frequency.
Kwisamkeli esikhulu samachiza emfazwe, impendulo ebangelwa luphawu olungena kwisamkeli ngobuninzi esahlukileyo kubuninzi besijingajingisi sasekhaya ngobuninzi be-IF. Uphawu, nangona kunjalo, likwicala eliphikisana nobuninzi bempendulo elungileyo.
