Abstract

L'invention a pour objet un dispositif électronique de mesure de temps comportant un oscillateur, un diviseur de fréquence et un dispositif de commutation commandé par la sortie du diviseur de fréquence. Le dispositif présente la particularité qu'il comporte un élément de mémoire prévu pour l'alimentation du diviseur de fréquence qui, en cas de défaillance de la tension d'alimentation du dispositif, maintient le diviseur de fréquence dans l'état qu'il a atteint, de sorte que ce diviseur de fréquence recommence à compter à partir de cet état lors de la reapparition de la tension d'alimentation. L'invention trouve une application dans la détermination d'intervalles de temps, par exemple pour la commande de processus déterminés.
