Abstract
L'invention concerne les circuits de synchronisation des récepteurs de télévision. Le circuit de l'invention comprend un diviseur 1, deux bascules 2 et 3, un circuit de retard 4 et des portes 5, 6 et 7. Ce circuit fournit en sortie un signal de synchronisation verticale présentant la phase et la fréquence appropriées, lorsqu'il reçoit à l'entrée le signal de synchronisation verticale séparé du signal vidéo, et un signal à une fréquence double de la fréquence de ligne. Application aux récepteurs de télévision.
