Abstract
Procédé et appareil de démodulation de signaux codés biphasés. Une boucle à verrouillage de phase numérique produit un signal d'horloge en phase avec le signal d'horloge du signal d'entrée codé biphasé. Le signal d'horloge provenant de la boucle à verrouillage de phase sert ensuite à dériver le signal de données du signal d'entrée codé biphasé, d'une manière augmentant la tolérance au désalignement des bords.
