Abstract

Dans un récepteur de télévision muni d'un circuit d'accord opérant par synthèse de fréquences et devant être accordé à l'aide de données de canal, si l'on combine judicieusement les commutateurs de sélection de programmes et les commutateurs de canal, l'établissement d'une relation visible entre le programme sélectionné et le canal correspondant est possible sans nécessiter l'emploi de circuits de reproduction distincts. Application aux récepteurs de télévision en couleur.
