Abstract

Générateur de transformées discrètes. Ce dispositif est destiné à engendrer les pseudo transformées de Mersenne Ak de séries de termes {an }. Les termes an , sont introduits dans un ordre prédéterminé et en série par bit, dans un circuit à recirculation SRI pourvu de prises. Les prises sont reliées aux entrées d'un additionneur ADD1, appartenant à un circuit d'accumulation série-parallèle, à travers un ensemble de commutateurs à deux positions SW2. Lesdites accumulations série-parallèles fournissent des termes Bk ** 1 et Bk **2 qui seront ensuite additionnés entre eux modulo 2**q-1 (q étant un nombre premier donné) et soustraits l'un de l'autre modulo 2** q+1, pour fournir des termes Ak **1 et Ak **2. Ces derniers termes sont introduits dans un circuit d'additions pondérées fournissant Ak (pour k Not= o). Traitement du signal.
