Abstract

L'invention concerne un circuit rythmeur à allongement et mise en attente. Un circuit rythmeur selon l'invention est caractérisé par un premier circuit 101 pour retarder un signal électronique d'un premier temps prédeterminé, un second circuit 102 couplé au premier pour retarder le signal électronique d'une seconde quantité prédéterminée, un troisième circuit électronique 108 couplé au premier circuit électronique pour produire un premier signal rectangulaire alternatif ayant une période prédeterminée et un quatrième circuit électronique 104 couplé au premier, au second et au troisième circuit électronique et répondant à un premier signal de demande pour augmenter la période du premier signal rectangulaire alternatif d'une quantité prédéterminée. Un circuit selon l'invention convient en particulier pour un ordinateur avec des équipements périphériques.
