ABSTRACT:
An FM wave received by an antenna is fed via an AGC circuit to a first FM demodulator and to a compensation signal generator which includes an envelope signal generator, a capacitor, a function generator, an analog multiplier, an SSB modulator, and a second FM demodulator so that the output signal of the compensation signal generator is added to the output signal obtained by the first FM demodulator to offset the multipath distortion contained in the received FM wave.
