Abstract

DECODEUR DE MODULATION DELTA QUI COMPORTE UN RESEAU INTEGRATEUR POURVU D'UN PREMIER CONDENSATEUR D'INTEGRATION QUI, D'UNE PART EST CONNECTE A UNE BORNE D'ENTREE DU RESEAU INTEGRATEUR ET QUI, D'AUTRE PART, EST MIS AU POTENTIEL DE MASSE PAR L'INTERMEDIAIRE D'UN SECOND CONDENSATEUR D'INTEGRATION. LES IMPULSIONS 1 ET LES IMPULSIONS 0 DU SIGNAL DE MODULATION DELTA FOURNIES AU DECODEUR SONT AMENEES A UN CIRCUIT DE SOURCE DE COURANT QUI PRODUIT UNE QUANTITE DE CHARGE POSITIVE A LA SUITE DE CHAQUE IMPULSION 1 ET UNE QUANTITE DE CHARGE NEGATIVE A LA SUITE DE CHAQUE IMPULSION 0. CES QUANTITES DE CHARGES SONT AMENEES PAR L'INTERMEDIAIRE D'UN RESEAU CORRECTEUR A LA BORNE D'ENTREE DU RESEAU INTEGRATEUR. LE RESEAU CORRECTEUR EST COMMANDE PAR LA TENSION V PAR L'INTERMEDIAIRE DU SECOND CONDENSATEUR D'INTEGRATION, DE SORTE QUE SI V EST POSITIF, LES QUANTITES DE CHARGE POSITIVE SONT DIMINUEES ETOU LES QUANTITES DE CHARGE NEGATIVE SONT AUGMENTEES ET SI V EST NEGATIF, LES QUANTITES DE CHARGE POSITIVE SONT AUGMENTEES ETOU LES QUANTITES DE CHARGE NEGATIVE SONT DIMINUEES. APPLICATION : TRANSMISSION D'INFORMATIONS.
