Abstract

Dans un récepteur comportant un circuit chercheur de stations au moyen duquel un groupe de données d'accord correspondant à des émetteurs déterminés peut être recherché, on utilise, en plus d'un détecteur d'intensité de champ, un détecteur de fréquence pour permettre le redémarrage rapide d'une opération de recherche lors d'un arrêt sur un émetteur dont la fréquence s'écarte quelque peu de la fréquence souhaitée. Application aux récepteurs radio à modulation de fréquence.
