Abstract

Le procédé consiste à transformer un signal analogique modulé en fréquence par des moyens purement numériques en un code numérique (DELTAN) proportionnel à l'écart (DELTAf) du signal de la fréquence intermédiaire (f). Le dispositif permettant de réaliser le procédé comporte un convertisseur (1), un comparateur (3), un diviseur de fréquence (5), un dispositif de mesure (6) de la durée des impulsions, un processeur (7), un diviseur de signaux (8) et un générateur (9) d'impulsions de synchronisation.
