Abstract

L'invention concerne un circuit numérique à semiconducteurs. Dans ce circuit comportant deux parties, un générateur de cadence T les commandant et dans lequel l'une des parties de circuit est formé par un registre à décalage SR, l'autre partie de circuit est formée par un compteur binaire DZ et est chargée par les impulsions de la cadence de transfert diamétre , le générateur de cadence T délivrant périodiquement une impulsion auxiliaire Ub , qui sert à la commande de la réception et/ou de la délivrance d'informations du registre à décalage SR. Application notamment aux orgues électroniques.
