Method for detecting/suppressing interference signals in stereo multiplex signals on stereo radio receivers compares unfiltered and low-pass filtered stereo multiplex signals to spot interfering signals in unfiltered signals.

摘要

The level of an unfiltered stereo multiplex signal (MPX) is compared in a comparator (V) with the level of a stereo multiplex signal (TX) filtered via a low-pass filter (TP). An interfering signal is detected in the unfiltered stereo multiplex signal if the difference between the level of the unfiltered stereo multiplex signal and the level of the stereo multiplex signal filtered via a low-pass filter exceeds a preset threshold. An Independent claim is also included for a stereo radio receiver for carrying out the method of the present invention.
