Abstract
An FM stereo receiver has a loop having a negative loop gain for the pilot signal contained in the input signal in the form of a frequency modulation. As a result thereof the frequency modulation of the input signal is reduced or suppressed by the pilot signal, so that the interference introduced by this pilot signal is also reduced or suppressed.
