Abstract

L'invention concerne un procédé et un appareil permettant de récupérer des informations d'horloge intégrées dans un signal numérique. Un ensemble d'impulsions stroboscopiques peut être généré par acheminement d'un générateur de limite à des éléments de retard avec des valeurs de retard augmentant progressivement. Un ensemble de verrous déclenché par des signaux retardés progressivement à partir du générateur de limite peut capturer des échantillons du signal de données. Un codeur peut convertir les échantillons en un mot représentant un temps limite et une polarité du signal échantillonné. Le mot représentant le temps limite peut être stocké en mémoire. Un accumulateur peut recueillir le temps limite moyen sur N échantillons. Le temps limite peut être ajusté sur une valeur de réalignement fixe de façon à former les informations d'horloge extraites, qui peuvent servir de pointeur aux mots stockés en mémoire.
