Abstract
L'invention concerne un circuit oscillateur à commande de phase automatique qui produit un signal d'horloge de sortie dont la phase et la fréquence varient avec celles d'un signal d'information d'entrée qui lui est appliqué Le cicuit comprend une borne d'entrée 64 recevant le signal d'information, un circuit d'accord 63 connecté à la borne d'entrée de façon à laisser passer le signal d'information d'entrée sous forme de signal accordé, et un générateur de signaux d'horloge connecté au circuit d'accord. Le circuit d'accord est un circuit à fréquence variable dont un dispositif d'entrée reçoit ledit signal d'information d'entrée, et dont un circuit d'entrée de commande reçoit un signal de commande Cv représentatif de la fréquence du signal d'information d'entrée Din, le circuit d'accord étant accordé sur la base du signal de commande de façon à laisser passer le signal d'information sous forme de signal accordé depuis une de ses sorties. Il est également prévu une boucle de correction de phase 70 66 afin de compenser les déphasages introduits par le circuit d'accord. L'invention s'applique notamment aux magnétoscopes numériques.
