Title: DEVICE FOR PROCESSING AN AUDIO SIGNAL ARISING FROM A RADIOFREQUENCE SIGNAL
Abstract:
Device (1) for processing an audio signal (8) arising from a radiofrequency signal (7), comprising: an instantaneous multi-path sensor (3) able to analyse the radiofrequency signal (7) so as to determine an instantaneous multi-path rate (9), an instantaneous filter block (5) able to attenuate the audio signal (8) according to an instantaneous attenuation which is an increasing function of the instantaneous multi-path rate (9), further comprising a mean multi-path sensor (4) able to determine a mean multi-path rate (10), and a mean filter block (6) able to attenuate the audio signal (8) according to a mean attenuation which is an increasing function of the mean multi-path rate (10). The invention also relates to a radio receiver comprising such a processing device (1).
