Abstract

L'invention concerne un montage dénommé filtre à action vocale destiné à modifier le spectre de fréquences de signaux électriques issus d'un générateur de manière à produire des sons dont les modulations sont analogues à celles de la voix humaine. Le filtre objet de l'invention comporte un filtre analogique 1 doté d'une fonction de transfert pouvant être modifié de manière continue, réversible et contrôlable au moyen d'organes de commande 3, 31 , 32 ,... 3x , ledit filtre analogique est suivi d'un filtre numérique 4 dont la fonction de transfert est échantillonnée par une horloge 6 génératrice d'impulsions à récurrence variable au moyen d'une commande externe 7 de sorte que, à sa sortie, les signaux obtenus amplifiés par un amplificateur de puissance, convertis en ondes sonores par un haut-parleur permet d'imiter certaines modulations de la voix humaine au moyen des commandes 3 et 7 lorsqu'elles sont actionnées.
