Abstract
In a radio receiver in which the received signal is converted by mixing into an intermediate frequency signal and/or a baseband signal, the degree of distortion of received disturbance signals in the receiver is temporarily changed and a recognition circuit is used which recognizes from the change in the signal gaining demodulation, caused by the change in the degree of distortion, whether the receiver is receiving spurious interference signals falling into the useful channel, and which, in the event of such a disturbance signal reception, initiates a suppression or reduction of the spurious interference signals.
