Abstract
a. Circuit de traitement de signaux pour créer un signal qui est fonction complexe de deux variables d'entrée. b. Circuit caractérisé par un premier moyen de stockage couplé à un générateur de fonction de transfert pour enregistrer une grandeur liée à la sortie de la fonction de transfert, un moyen d'alimentation et de sélection comportant un circuit pour fournir un second signal d'entrée au générateur de fonction de transfert et un moyen couplé au moyen d'enregistrement pour multiplier la sortie du générateur de fonction de transfert par un facteur lié à la grandeur enregistrée et créer une signal de sortie complexe.
