Abstract

L'invention concerne les dispositifs de traitement de signaux. Le dispositif de l'invention comprend un circuit d'entrée lA et un circuit de calcul 1B qui comporte un certain nombre d'unités de calcul U0 , U1 , ... UN-1 formées par des dispositifs à couplage de charge à électrodes divisées. Le dispositif de traitement de signal multiplie les échantillons d'entrée par un ensemble de coefficients constants, ce qui permet de réaliser facilement un produit de matrices. Application à la transformation de Fourier rapide.
