Abstract

Dispositif permettant d'engendrer un bruit analogique à partir d'un processus ponctuel, la distribution dudit bruit étant prédéterminable. Selon l'invention, ce dispositif est caractérisé en ce qu'il comprend une source de bruit, un premier générateur ou générateur d'impulsions aléatoires, un second générateur ou générateur de motif ou de fonction, la sortie de la source de bruit étant reliée à l'entrée du premier générateur, la sortie du premier générateur étant reliée à l'entrée du second générateur, et la sortie du second générateur constituant la sortie de l'ensemble dudit dispositif. Application au codage et à la transmission d'informations.
