Abstract

Oscillateur à modulation angulaire. L'oscillateur à modulation angulaire est alimenté avec un signal de modulation de façon que ni la stabilité de la fréquence de l'oscillateur de référence, ni la boucle de commande ne soient altérées. Dans le circuit à modulation angulaire d'un oscillateur à boucle verrouillée en phase, constitué d'un oscillateur à commande par tension, d'un diviseur, d'un discriminateur de phase, d'une boucle de filtrage et d'un oscillateur de référence agissant par l'intermédiaire d'un diviseur fixe sur le discriminateur de phase, le signal de référence sortant du diviseur fixe est modulé par le signal de modulation appliqué au modulateur de phase. Application aux oscillateurs à modulation angulaire.
