Abstract

SYNTHETISEUR DE FREQUENCE A BOUCLES D'ASSERVISSEMENT DE PHASE MULTIPLES PRESENTANT LA PARTICULARITE DE PERMETTRE UNE LARGE EXPLORATION DE FREQUENCE SANS PHENOMENE DE DISCONTINUITE DE FREQUENCE OU D'AMPLITUDE. IL COMPORTE AU MOINS TROIS OSCILLATEURS ASSERVIS EN PHASE, LE PREMIER ASSURANT LA GENERATION DES PLUS PETITS PAS, LE SECOND CELLE DES GRANDS PAS ET LE TROISIEME EFFECTUANT LA SOMME ALGEBRIQUE DES FREQUENCES DES DEUX PREMIERS. LE PREMIER OSCILLATEUR O, LORS D'UNE INCREMENTATION POSITIVE DE LA FREQUENCE DE SORTIE, VOIT SA FREQUENCE AUGMENTER PUIS DIMINUER ET AINSI DE SUITE, EN DEUX MODES DE FONCTIONNEMENT SUCCESSIFS PARFAITEMENT ENCHAINES. APPLICATION A LA REALISATION D'UN VOBULATEUR PROGRAMMABLE.
