Abstract
CE GENERATEUR EST DESTINE A PRODUIRE DES GROUPES D'IMPULSIONS PRESENTANT DES LARGEURS DE TEMPS ET DES RELATIONS SOUHAITABLES JUSQU'A DES VITESSES EXTREMEMENT ELEVEES ET AVEC UNE PRECISION DE QUELQUES NANOSECONDES, PAR EXEMPLE DANS DES APPLICATIONS DE RADAR. IL FONCTIONNE SUR UNE FREQUENCE DE COMMANDE DERIVEE D'UN OSCILLATEUR A QUARTZ. IL EST DIVISE EN UN PREMIER DISPOSITIF SERVANT A DETERMINER L'ESPACE DE TEMPS ENTRE LES GROUPES D'IMPULSIONS ET UN SECOND DISPOSITIF COMMANDE PAR LE PREMIER POUR DETERMINER LES LARGEURS D'IMPULSIONS ET POUR COMMANDER DES DISPOSITIFS GENERATEURS D'IMPULSIONS. DES VALEURS NUMERIQUES D'ESPACE DE TEMPS DIFFERENTES ET DE VALEURS NUMERIQUES DE LARGEUR D'IMPULSION DIFFERENTES PEUVENT ETRE PROGRAMMEES DANS DES MEMOIRES PROM DES DISPOSITIFS ET PEUVENT ETRE SELECTIONNEES PAR LE MEME JEU DE SIGNAUX DE MODE DE FONCTIONNEMENT. L'ESPACE DE TEMPS PEUT EGALEMENT ETRE OPTIMALISE AU MOYEN D'UN CALCULATEUR EXTERIEUR COMMANDANT UNE AUTRE MEMOIRE PROM CONTENANT DES INFORMATIONS QUI PEUVENT ETRE COMBINEES AVEC LES INFORMATIONS PROM D'ESPACE DE TEMPS.
