ABSTRACT:
Disclosed is an automatic noise reduction system of FM stereo receiver wherein the input level and carrier frequency deviation of an FM stereo transmission signal received by an antenna are detected and, when at least either one of the input level and carrier frequency deviation decreases, the separation between first and second audio outputs of a stereo demodulator for demodulating the FM stereo transmission signal is decreased and simultaneously high frequency components on the first and second audio outputs are attenuated.
