Abstract

Ce montage pour la génération de séquences aléatoires d'octets comprend un premier oscillateur (OSZ1) et un second oscillateur (VCO1) dont les sorties sont connectées aux entrées d'un détecteur de phase (PD) qui crée la séquence aléatoire d'octets. Le second oscillateur (VCO1) est modulé en fréquence.
