Abstract

Dispositif permettant de stabiliser la fréquence d'un oscillateur ou d'un générateur de signaux périodiques. La présente invention est une variante des boucles d'asservissement de phase qui stabilisent un oscillateur en comparant en phase son signal à celui d'un oscillateur de référence. Le principe de l'invention consiste à utiliser comme signal de référence le signal de l'oscillateur lui-même de façon à contre-réactionner l'oscillateur par un signal d'erreur provenant de la comparaison en phase de signaux issus de l'oscillateur à des instants différents. L'invention peut être utilisée avec tout oscillateur ou générateur dont la fréquence est commandable électriquement par un courant ou une tension.
