Abstract

Dispositif de télécommande permettant la détection et la suppression des interférences et erreurs d'impulsions. Le dispositif est caractérisé par le fait que la variation relative de fréquence d'un second oscillateur est faite par rapport à celle d'un premier oscillateur, que le << zéro >> binaire est attribué à un premier espacement prédéterminé entre impulsions T, tandis que le << un >> binaire est attribué à un second espacement entre impulsions 2T, chaque mot de commande étant précédé d'une impulsion de départ située à une distance T de l'espacement de la première impulsion et étant suivi par une impulsion finale à une distance égale à 3T. Le récepteur B comprend un circuit de mesure simple de l'espacement de la première impulsion reçue et la durée de l'espacement entre impulsions mesurée sert de base de temps dans un circuit de détection et de suppression d'erreur d'impulsion. Application aux dispositifs de télécommande à infrarouges des postes de radio ou de télévision.
