Abstract
L'invention concerne les récepteurs radioélectriques. Un circuit de sélection automatique de signal pour un récepteur radioélectrique comprend notamment un circuit de traitement il qui applique à un diviseur programmable 4 un nombre qui correspond au rang de division que doit présenter ce diviseur pour accorder le tuner 2 du récepteur sur le signal à recevoir. Le circuit de traitement il attaque également un générateur de caractères 16 qui affiche sur le dispositif d'affichage 9 des informations relatives aux réglages du récepteur, ainsi qu'à la situation d'une mémoire de présélection de stations 12. Application aux récepteurs de télévision.
