Abstract

L'invention concerne un agencement de correction de la trame d'un appareil de déviation de télévision, qui comprend un générateur produisant des signaux de déviation à la fréquence horizontale, couplé à un enroulement de déviation horizontale qui est sensible aux signaux de déviation pour produire des impulsions récurrentes de retour; un circuit de charge couplé à une sortie du générateur, des variations de la charge du circuit faisant varier la durée des impulsions de retour de façon à provoquer une distorsion de la trame. Selon l'invention, un moyen 60 de détection de la durée des impulsions de retour est couplé au générateur 24 de courant de déviation horizontale pour produire un signal de commande; un moyen d'impédance réglable 32, 36, 40, 42, 44 est couplé à une sortie du générateur 24 et au moyen de détection 60 et est sensible au signal de commande pour compenser la distorsion de la trame. L'invention s'applique notamment aux téléviseurs couleurs.
