Abstract
POUR L'ETALONNAGE AUTOMATIQUE D'UN CONVERTISSEUR ANALOGIQUE-NUMERIQUE, ON PROCEDE A LA MESURE D'UN PARAMETRE D'ETALONNAGE ANALOGIQUE, ET L'ON COMPARE LE SIGNAL NUMERIQUE A UN SIGNAL D'ETALONNAGE NUMERIQUE APPARTENANT AUDIT PARAMETRE. UN SIGNAL DE DIFFERENCE NUMERIQUE EST FOURNI A UN REGISTRE POUR INFLUENCER LA CAPACITE DE COMPTAGE DE CE DERNIER, TANDIS QUE LE CONTENU EN IMPULSIONS COMPTEES AU COURS DE LA MESURE, REPRESENTE LUI AUSSI UN DES PARAMETRES INTERVENANT DANS LA CONVERSION ANALOGIQUE-NUMERIQUE. PAR SUITE DU CARACTERE ENTIEREMENT NUMERIQUE DE L'ETALONNAGE, CE DERNIER PEUT AVOIR LIEU RAPIDEMENT ET DE FACON PRECISE. APPLICATION : MULTIMETRES.
