Abstract

L'invention concerne les circuits de déviation horizontale des récepteurs de télévision. Le circuit de l'invention comprend un circuit de déviation proprement dit, L1-C11-C12, et un autre circuit accordé, L2-C21-C22. Le courant qui traverse la bobine de déviation L1 est modulé pour corriger distorsion en coussin de l'image formée, tandis que le courant qui traverse la bobine L2 est maintenu à une valeur pratiquement constante. Application aux récepteurs de télévision en couleurs.
