The method involves high-pass filtering an input signal which is affected by multi-path disturbances, so that low-frequency signal portions of the input signal are suppressed. The filtered input signal is amplified, so that a level of the high-frequency signal portions is increased. The amplified and filtered input signal is searched for characteristic pulses which appear at multi-path disturbances. The pulses, if they comprise or exceed a previously determined level, are recorded and are broadened, whereby the signal energy of the pulses is enlarged. Further signals are won from the signal, over respectively at least one time-constant element, for influencing a processing of the radio signal, especially for a dynamic high-cut, stereo-blending, or a volume control, i.e. muting. |
