Abstract
A distortion reducing circuit in an FM receiver comprises a distortion detector for receiving the output of an FM demodulating circuit. The distortion detector comprises a high pass filter, the output of which is applied to a capacitor so that the same is rapidly charged. The conduction of the transistor is changed as a function of the charge voltage across the capacitor and a high frequency component in the output of the FM demodulating circuit is reduced in association with the conduction of the transistor.
