Title (EN) DEVICE FOR PROCESSING AN AUDIO SIGNAL ARISING FROM A RADIOFREQUENCE SIGNAL
(FR) DISPOSITIF DE TRAITEMENT D'UN SIGNAL AUDIO ISSU D'UN SIGNAL RADIOFRÉQUENCE
Abstract: front page image
(EN)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).
(FR)Dispositif de traitement (1 ) pour un signal audio (8) issu d'un signal radiofréquence (7), comprenant : un capteur de multi-trajet instantané (3) apte à analyser le signal radiofréquence (7) pour déterminer un taux de multi-trajet instantané (9), un bloc filtre instantané (5) apte à atténuer le signal audio (8) selon une atténuation instantanée fonction croissante du taux de multi-trajet instantané (9), comprenant encore un capteur de multi-trajet moyen (4) apte à déterminer un taux de multi-trajet moyen (10), et un bloc filtre moyen (6) apte à atténuer le signal audio (8) selon une atténuation moyenne fonction croissante du taux de multi-trajet moyen (10). L'invention concerne également un récepteur radio comprenant un tel dispositif de traitement (1 )
