Abstract
A control circuit in an FM radio receiver includes a current mirror circuit which extracts a ripple component caused by a multipath disturbance and superposed on an S-meter output voltage from an intermediate frequency amplifier/detector of the FM radio receiver, and decreases the S-meter output voltage in response to the degree of the ripple component to use the decreased S-meter output voltage as a control voltage for control of separation and high-cut operations of a stereo demodulating stage of the FM radio receiver.
