Abstract

CE DISPOSITIF COMPORTE UN GENERATEUR DE RAMPES CONSTITUE, DE PREFERENCE, PAR UNE CELLULE D'INTEGRATION RC QUI, A CHAQUE VALEUR DU SIGNAL LOGIQUE D'ENTREE, FAIT CORRESPONDRE UNE RAMPE MONTANTE OU DESCENDANTE DETERMINEE. UN COMPARATEUR COMPARE A CHAQUE INSTANT LE SIGNAL DE SORTIE DE CE GENERATEUR AVEC LA VALEUR MOYENNE DE CE SIGNAL DE SORTIE. APPLICATION : UTILISABLE POUR LA TRANSMISSION DE SIGNAUX D'HORLOGE.
