Abstract

L'INVENTION CONCERNE UN DISPOSITIF DE FILTRAGE A TRANSFERT DE CHARGES MULTIPLEXE. UN SOMMATEUR A ADDITIONNANT ALTERNATIVEMENT: UN PREMIER SIGNAL D'ENTREE, E, ECHANTILLONNE, AVEC UN SIGNAL ECHANTILLONNE CORRESPONDANT PROVENANT DE LA PARTIE RECURSIVE D'UN FILTRE HYBRIDE, PUIS UN SECOND SIGNAL, E, ECHANTILLONNE ET RETARDE, AVEC LE SIGNAL ECHANTILLONNE CORRESPONDANT EN PROVENANCE DE LA PARTIE RECURSIVE DU MEME FILTRE HYBRIDE. LA PARTIE NON RECURSIVE, SOMMEE PAR UN AMPLIFICATEUR DE LECTURE, A, DONT LA SORTIE CONSTITUE LA SORTIE DU FILTRE, EST DEMULTIPLEXEE ET RETARDEE POUR LA RESTITUTION DU PREMIER SIGNAL DE SORTIE EN O ET SEULEMENT DEMULTIPLEXEE POUR CELLE DU SECOND SIGNAL DE SORTIE EN O. APPLICATION AUX MODULATEURS, DEMODULATEURS A BANDE LATERALE UNIQUE.
