Title: Unnecessary interference noise eliminating system for fm stereo receiver
Inventor: INOUE SHIGEKI
IPC: H04B1/16
Filed: 1981-03-27
Abstract: PURPOSE:To achieve a reception state with high quality, by providing a switch changing over if a low-pass filter is inserted between an FM detector and a stereo demodulator. CONSTITUTION:An output of an FM detector 1 is inputted to a stereo demodulator 3 via a switch 6 without passing through a filter 2 normally. If an interference wave adjacent to a reception frequency is present, a higher frequency component than an L-R component out of output signals of the FM detector 1 receives interference. A high-pass filter 4 detects if there is any interference wave in the higher frequency component than the L-R component. If the interference wave is detected, the low-pass filter 2 is inserted between the FM detector 1 and the stereo demodulator 3 and the switch 6 is controlled so that the interference wave can be rejected.
