PROCEDURES FOR THE REDUCTION OF RECOVERY AUTHORISATIONS, MECHANICAL AUTHORISATIONS, FOR THE RECEIPT OF A RURAL FUNCTION SIGNAL, AND FOR THE PURPOSE OF THE PROCEDURE

摘要

The invention relates to a method for detecting and reducing reception interferences, especially multiway reception interferences, in an input signal (E) of a radio receiver. According to said method, a reception interference of this type is detected in a detector device (10) and a corresponding detector signal (MWS, AMS, MKS) is transmitted to a processing device (20) which then evaluates this detector signal (MWS, AMS, MKS). A corresponding control signal (S) is then generated by the processing device (20) and transmitted to an audio unit (30), which generates an audio signal lying in a frequency interval delimited by a lower limit frequency (GO") and an upper limit frequency (GO'). The audio unit (30) lowers the level of the audio signal (A) generated by the same using the input signal (E) within the frequency range above a lowered upper limit frequency (G1', G2') below the aforementioned upper limit frequency (GO') of the audio signal (A). According to the invention, the level of the audio signal (A) is lowered in the range below a lower limit frequency that has been raised above the aforementioned lower limit frequency (GO") at the same time as the level of the audio signal (A) is lowered in the frequency range above the lowered upper limit frequency (G1', G2').
