Abstract

Selon l'invention, on prévoit un circuit déflecteur (40), un moyen (24c) produisant un signal de synchronisation, un moyen (30) répondant au signal de synchronisation pour produire un signal de commande à une fréquence qui ne change pas quand le circuit de déviation fonctionne à l'une ou l'autre des deux fréquences de balayage; et une alimentation en courant de commutation (20) ne changeant pas de fréquence, en synchronisme avec le courant de balayage. L'invention s'applique notamment aux moniteurs vidéo.
