An FMX stereophonic receiver for receiving an FMX stereophonic broadcast signal, which includes a stereo sum signal, a stereo difference signal and a compressed stereo difference signal, is disclosed. When multipath interference takes place, noise signal will be produced, which adversely affects on a level control of an added signal of the stereo difference signal and the compressed stereo difference signal. The disclosed receiver includes a detector for detecting the multipath noise signal contained in the FMX stereophonic broadcast signal. When the multipath noise signal is detected, FMX receiving mode is automatically changed to FM receiving mode by a selecting means, so as to reduce the affect of the noise signal. |
