Abstract

L'INVENTION CONCERNE UN SYSTEME ACTIF DE TRAITEMENT ANALOGIQUE DE SIGNAUX, AVEC ANNULATION DES PARASITES. IL COMPORTE DEUX CIRCUITS DE TRAITEMENT IDENTIQUES ET UN DISPOSITIF QUI LES COMMUTE ALTERNATIVEMENT ENTRE UN MODE DE TRAITEMENT ET UN MODE D'ANNULATION DE TENSION PARASITE DANS LEQUEL UN CONDENSATEUR EST CHARGE A LA VALEUR MOYENNE DE LA TENSION PARASITE DE MANIERE A ANNULER CETTE TENSION DANS LE MODE DE TRAITEMENT. L'INVENTION S'APPLIQUE NOTAMMENT A UN AMPLIFICATEUR A FAIBLE BRUIT.
