Abstract

Générateur de signaux électriques modulé en fréquence en 8 comportant deux oscillateurs 5 et 1, le premier 5 délivrant la fréquence de sortie modulée et attaquant un mélangeur 2 qui reçoit par ailleurs la sortie du second oscillateur 1. Ce dernier est asservi en phase par une boucle comportant le mélangeur 2, un filtre 3 et un premier comparateur de phase 4 qui reçoit une fréquence intermédiaire N2 p. Le premier oscillateur est asservi par une boucle comportant le second oscillateur 1 suivi d'un diviseur de fréquence réglable 6 et d'un second comparateur 8 recevant une fréquence de référence P. Application à la réalisation d'un synthétiseur à résolution élevée modulé en fréquence.
