Abstract

Dispositif pour effectuer le produit de convolution numérique C1 X1 + ... C n X dans lequel les coefficients numériques Ci sont constants et les multiplicateurs Xi peuvent être variables, comportant au moins un accumulateur. Il comprend un unique accumulateur relié à la sortie d'une mémoire morte dans laquelle sont enregistrées les diverses valeurs des combinaisons des coefficients C1 ... Cn avec 0 et 1, ainsi que des moyens pour appliquer aux entrées d'adressage de la mémoire morte les poids de même rang des multiplicateurs X1 ... X n . Applications aux installations de filtrage numérique, de modulation numérique, d'analyse spectrale, et d'égalisation automatique.
