Abstract

La présente invention concerne des circuits logiques pour commander plusieurs commutateurs à semi-conducteur. Le circuit logique est caractérisé par le fait qu'il combine : - une entrée à laquelle on applique, en cours d'utilisation, des signaux d'impulsions discernables de composition de numéro sur un cadran et de remise à zéro, - un certain nombre de sorties auxquelles sont connectés, en cours d'utilisation, les commutateurs à semi-conducteur respectifs, - des moyens destinés à distinguer entre eux les signaux de composition de numéro sur un cadran et les signaux de remise à zéro, - des moyens pour commuter de façon séquentielle la condition des sorties en réponse aux signaux d'impulsion de composition de numéro sur un cadran, - et des moyens pour remettre les sorties à une condition donnée en réponse au signal d'impulsion de remise à zéro. Application à la télévision par câble, notamment.
