Title (EN) DSP-BASED DATA RECOVERY
(FR) RECUPERATION DE DONNEES BASEES SUR DSP
Abstract: front page image
(EN)A bit clock recovery apparatus for digital storage readout employing sync frames, where an oversampled readout signal is stored in memory, sync patterns are located in the signal using DSP means, distances of consecutive sync pattern locations are calculated, and bit clock is recovered from these distances and the knowledge about the data framing structure.
(FR)Dispositif de récupération d'horloge binaire conçu pour effectuer une extraction hors d'une mémoire numérique mettant en application des blocs de synchronisation, ce qui consiste à mettre en mémoire un signal d'extraction suréchantillonné, à placer dans ce signal des configurations de synchronisation au moyen de DSP à calculer les distances d'emplacement consécutifs de configurations de synchronisation et à récupérer l'horloge binaire de ces distances et de la connaissance acquise à propos de la structure des blocs de données.
