Abstract

L'invention a pour objet un filtre récursif dans lequel l'étage d'entrée réalise la ré-injection et la différence des signaux fournis par le filtre proprement dit L'étage d'entrée est constitué par deux canaux 1 et 2 parallèles dans lesquels les charges sont transférées, placés devant le filtre proprement dit Chacun des canaux comporte une diode Di d'injection des charges, deux électrodes G 1 , G2 ; G3 , G4 et une diode Dr placée entre ces électrodes. L'un des canaux 1 réalise l'injection du signal d'entrée E dans le dispositif. L'autre canal 2 est affecté à la ré-injection et reçoit sur ses deux électrodes G3 , G4 les signaux S**+, S**- fournis respectivement par les deux parties des électrodes coupées du filtre, dont il réalise à la fois l'injection et la différence. L'invention est notamment applicable aux transmissions téléphoniques.
