Abstract
L'invention concerne un circuit correcteur de phase différentielle. Ce circuit se caractérise en ce qu'il comprend des moyens 24, 28, 30 pour déphaser un signal de télévision de manière réglable et des moyens 14 répondant à ce signal 22 et au signal déphasé 34 à distorsion minimale et à déphasage commandé. Ce circuit s'applique à des systèmes de télévision en couleur à commande automatique.
