An apparatus for frequency band reduction of a voice signal having an upper and lower band limit including a voice signal input. A clipping circuit clips the positive and negative peaks of the voice signal connected to the voice signal input. A bandpass filter is connected to the clipping circuit for rejecting harmonics created by the clipping circuit. A low and high end roll-off filter device is provided for producing a given db/octave frequency roll off at the lower bandlimit. The geometric mean value of the upper and lower bandlimit falls within a given lowerand a given upper frequency range.

Dispositif pour réduire la bande de fréquences d'un signal vocal ayant des limites supérieure et inférieure de bande, et comprenant une entrée de signal vocal. Un circuit d'écrêtage supprime les crêtes positives et négatives du signal vocal associé à l'entrée de signal vocal. Un filtre passe-bande connecté au circuit d'écrêtage rejette les harmoniques produites par ce dernier. Un dispositif de filtrage à coupure progressive de limites inférieure et supérieure produit à la limite inférieure de la bande une coupure progressive de fréquence à une valeur donnée de db/octave. La valeur moyenne géométrique des limites supérieure et inférieure de la bande est comprise entre une bande passante inférieure donnée et une bande passante supérieure donnée.
