Abstract
L'invention concerne un circuit électrique destiné à produire un signal de sortie de fréquence variable. Ce circuit comporte une boucle à verrouillage de phase comprenant un oscillateur commandé, un diviseur de fréquence et un comparateur de phase. Un circuit de commande établit le facteur de division du diviseur et le modifie périodiquement d'une unité en plus et d'une unité en moins de manière que la fréquence moyenne de sortie soit égale à la fréquence voulue Applications à la production de signaux à haute fréquence variable.
