Abstract

Il comporte un premier circuit oscillant comprenant la bobine de déviation et un condensateur, et un second circuit oscillant comportant une autre bobine avec un second condensateur. Les fréquences d'accord des deux circuits oscillants sont indépendantes et une diode est prévue pour transmettre de l'énergie du second circuit oscillant au premier, de manière à influencer le courant en dents de scie dans la bobine de déviation en modifiant l'énergie transmise à chaque cycle. L'invention s'applique notamment au circuit de balayage horizontal d'un récepteur de télévision en couleurs.
