Abstract

L'invention concerne un circuit de commande à distance de fonctions déterminées d'un récepteur de signaux. Ce circuit de commande consiste en un circuit intégré qui comporte un discriminateur de fréquence destiné à détecter la fréquence d'un signal de commande émis à distance ou émis localement par un circuit de commande de fréquence associé avec un oscillateur variable inclus dans le circuit intégré et un modulateur d'impulsions de sélection qui délivre un train d'impulsions dont le nombre est fonction de la fréquence du signal de commande reçu. Le nombre des bornes d'entrée du circuit intégré est ainsi considérablement réduit. L'invention s'applique notamment à des récepteurs de télévision.
