Title: Stereo demultiplexer

Abstract: For the noise reduction of an audio signal generated by stereo-demultiplexing of a frequency-modulated stereo multiplex signal (S.sub.FM(t)) a filtering within the signal path to generate the stereo difference signal (u.sub.d(t)) is performed that determines a weight with which the upper sideband (u.sub.d,u(t)) and the lower sideband (u.sub.d,l(t)) of the amplitude modulated stereo-difference signal are weighted with different weighting factors that are dependent on the frequency.
