Abstract

Disposition de circuit pour la mise en phase de deux ou plusieurs chaînes de comptage pilotées par des signaux de temporisation de même fréquence présentant un rapport de phase casuel. Elle comprend pour chaque chaîne de comptage les circuits suivants placés en cascade entre eux : un circuit d'acquisition de l'alignement, un circuit de contrôle preset, la chaîne de comptage pilotée par le signal de temporisation et un circuit générateur de signaux de synchronisme, à chaque chaîne de comptage sont associés une chaîne de comparaison, pilotée par le même signal de temporisation, et un circuit de comparaison apte à émettre un signal d'alarme.
