Abstract

L'invention a pour objet un circuit de correction de distorsion en coussinet d'une image d'un récepteur de télévision. Ce circuit 130 comprend une impédance 131 commutable montée en série avec un bobinage de déviation. Une partie de l'impulsion de tension de retour apparaît aux bornes de l'impédance. Un transformateur 96 a son bobinage primaire relié à la sortie du générateur de déviation, et aux bornes de son bobinage secondaire apparaît une partie de l'impulsion de retour. Une résistance 133 d'amortissement du circuit de correction est montée entre le bobinage secondaire 96d du transformateur et l'impédance 131. L'invention s'applique notamment aux récepteurs de télévision.
