Abstract

SYSTEME POUR L'ADRESSAGE D'UNE MEMOIRE NUMERIQUE A L'AIDE D'UN SIGNAL ANALOGUE ENTRANT ET POUR LA TRANSFORMATION DE LA SORTIE NUMERIQUE DE LA MEMOIRE EN UN SIGNAL ANALOGIQUE, QUI COMPREND UN CONVERTISSEUR NUMERIQUE-ANALOGIQUE, CE SYSTEME ETANT CARACTERISE EN CE QU'IL COMPREND UN COMPARATEUR COMPORTANT UNE PREMIERE BORNE D'ENTREE RELIEE A LA BORNE DE SORTIE DU CONVERTISSEUR NUMERIQUE-ANALOGIQUE ET UNE SECONDE BORNE D'ENTREE RELIEE AU SIGNAL D'ADRESSAGE ANALOGIQUE; DES MOYENS POUR ENGENDRER UN NOMBRE NUMERIQUE EN REPONSE AU SIGNAL DE SORTIE DU COMPARATEUR, CES MOYENS COMPORTANT UNE BORNE DE SORTIE POUR COUPLER LE NOMBRE NUMERIQUE A LA BORNE D'ENTREE D'ADRESSAGE DE LA MEMOIRE ET DES MOYENS DE COMMUTATION POUR COMMUTER ALTERNATIVEMENT LA BORNE D'ENTREE DU CONVERTISSEUR NUMERIQUE-ANALOGIQUE A LA BORNE DE SORTIE DE LA MEMOIRE NUMERIQUE ET AUX MOYENS ENGENDRANT CE NOMBRE NUMERIQUE.
