ABSTRACT:
In a radio receiver in which the received signal is converted by mixing into an intermediate frequency signal and/or a baseband signal, and in which an apparatus is provided which generates an intermediate frequency signal and/or baseband signal and derives therefrom a control signal for suppression or reduction of interfering disturbances, the signal fed to the apparatus is distorted in the apparatus in such a way that the signal distortion effected in the apparatus is greater than the distortion to which the signal fed to the receiver is subjected in the receiving section of the receiver.
