Abstract

L'invention concerne le filtrage des signaux audiofréquences. Le dispositif de l'invention comprend essentiellement un filtre passe-bas 32 qui reçoit un signal limité en amplitude, un compensateur de depassement 34 qui soustrait du signal de sortie du filtre 32 la composante qui correspond à un dépassement d'amplitude, et un filtre passe-bas 36 qui présente un retard constant pour toutes les fréquences transmises. Le signal filtré qui apparaît en sortie du filtre 36 ne présente aucun dépassement Application à la radiodiffusion stéréophonique en modulation de fréquence.
