Abstract

LE FILTRE COMPORTE UN ELEMENT DE LIAISON 4 POUR TRANSMETTRE LES ONDES ACOUSTIQUES DE SURFACE D'UN CANAL ACOUSTIQUE 3 DANS UN AUTRE CANAL ACOUSTIQUE 5 AVEC FORMATION SIMULTANEE DE LA CARACTERISTIQUE AMPLITUDE-FREQUENCE DU FILTRE. L'ELEMENT DE LIAISON 4 COMPORTE DEUX RANGEES 21, 24 D'ELECTRODES 22, 23 ET 25, 26. CHAQUE RANGEE 21, 24 SE DISPOSE DANS LE CANAL ACOUSTIQUE 3, 5 RESPECTIF ET A DEUX GROUPES D'ELECTRODES 22, 23 ET 25, 26 PARALLELES RESPECTIVEMENT A DES ELECTRODES 10, 11 ET 16, 17 DES CONVERTISSEURS D'ENTREE 2 ET DE SORTIE 6 A STRUCTURE INTERDIGITALE DISPOSES, RESPECTIVEMENT, DANS LES PREMIER ET DEUXIEME 5 CANAUX ACOUSTIQUES. LES ELECTRODES 23 ET 26 D'UN GROUPE DE CHAQUE RANGEE 21 ET 24 DE L'ELEMENT DE LIAISON 4 SONT RESPECTIVEMENT DISPOSEES ENTRE LES ELECTRODES 22 ET 25 DE L'AUTRE GROUPE DE LA MEME RANGEE 21 ET 24 ET FORMENT AVEC ELLES DES ZONES SE RECOUVRANT DE LONGUEUR VARIABLE L, AU MOINS, DANS UNE RANGEE 21, ET A CETTE RANGEE D'ELECTRODES 22, 23 DU CONVERTISSEUR 2 RESPECTIF CORRESPOND UNE RANGEE 9 D'ELECTRODES 10, 11 AYANT DES ZONES DE RECOUVREMENT DE LONGUEUR CONSTANTE L.
