Abstract

L'invention concerne un convolueur acousto-électrique multi-canal. Le convolueur selon l'invention a une région efficace relativement longue d'interaction d'ondes acoustiques de surface se propageant en sens inverses, c'est-à-dire un produit temps-largeur de bande relativement important, Obtenu par répartition d'un coupleur, par exemple à bandes plates ou comprenant un arrangement de prises de transducteurs à électrodes imbriquées, sur plusieurs convolueurs acousto-électriques monocanaux montés en parallèle. Application aux convolueurs utilisés pour les traitements de signaux par convolution.
