Abstract

UNE MONTRE ELECTRONIQUE COMPRENANT UN CIRCUIT DE MONTRE ET UN DISPOSITIF D'AFFICHAGE EST PREVUE QUI COMPORTE EN OUTRE UN DISPOSITIF DE MODIFICATION AUTOMATIQUE DE L'HEURE. LE DISPOSITIF DE MODIFICATION COMPREND UN RECEPTEUR 7, UN FILTRE 9 POUR LAISSER PASSER SEULEMENT LA COMPOSANTE DU SIGNAL PROVENANT DU RECEPTEUR QUI A LA MEME FREQUENCE QU'UN SIGNAL D'ANNONCE DE L'HEURE, UN DISCRIMINATEUR DE HAUTEUR D'IMPULSION 10 POUR CONVERTIR UN SIGNAL DE SORTIE DU FILTRE EN SIGNAL A DEUX NIVEAUX EN FONCTION DE L'AMPLITUDE DU SIGNAL DE SORTIE AU-DESSUS D'UN CERTAIN NIVEAU DE SEUIL, UN CIRCUIT DE DISCRIMINATION DE PROFIL D'ANNONCE DE L'HEURE 11 REPONDANT AU SIGNAL A DEUX NIVEAUX PROVENANT DU DISCRIMINATEUR POUR DETERMINER LA PRESENCE D'UN PROFIL D'ANNONCE DE L'HEURE SUR LA BASE DE LA DUREE DES SIGNAUX A DEUX NIVEAUX ET DE L'INTERVALLE DE TEMPS ENTRE CES SIGNAUX, ET UN CIRCUIT DE COMMANDE ET DE MODIFICATION DE L'INDICATION "SECONDES" 12 POUR MODIFIER L'INDICATION "SECONDES" DE LA MONTRE EN REPONSE A UN SIGNAL DE SORTIE PROVENANT DU CIRCUIT DE DISCRIMINATION.
