ABSTRACT:
Circuitry for controlling the intermediate frequency of an FM receiver comprising modulating means for frequency modulating the intermediate frequency signal with a modulating signal of predetermined frequency; detecting means for detecting the absolute amount of distortion incurred by the modulating signal of predetermined frequency at the intermediate frequency amplification stage of the FM receiver; and control means for changing the intermediate frequency by incremental amounts to control the intermediate frequency so that the distortion at the intermediate frequency amplification stage is minimized in accordance with the increase or decrease in the distortion detected by the detecting means.
