Abstract

L'invention concerne une identification numérique de fréquence. Pour former un train d'impulsions binaires à la fréquence de la tension alternative, on amène cette dernière à un amplificateur V à la suite duquel est monté un limiteur B. Pour balayer ce train d'impulsions binaires, ce dernier est amené aux entrées de données de deux registres à décalage SRI, SR2, un premier train d'impulsions de rythme étant amené à l'entrée de rythme du deuxième registre SR2, est amené un deuxième train d'impulsions de rythme déphasé de 180 degrés par rapport au premier. L'invention est utilisée pour l'identification numérique de la fréquence d'une tension alternative.
