Abstract
L'invention concerne un appareil de sélection de canal destiné à plusieurs dispositifs d'accord. L'appareil comporte au moins un jeu de commutateurs de sélection et un jeu de potentiomètres produisant des tensions d'accord. Ces tensions d accord sont échantillonnées périodiquement et filtrées pour être appliquées séparément à des éléments de réactance variable faisant partie des circuits d'accord associes. L'invention s'applique notamment à des récepteurs de télévision associés avec des enregistreurs d'image sur bande magnétique.
