Abstract

La présente invention concerne un dispositif de compensation d'un signal de sortie d'un codeur magnétique, le dispositif comprenant : un compensateur de signal pour transmettre un signal de sortie d'un codeur magnétique à un filtre passe-bas, déterminer des valeurs maximales et minimales des amplitudes pour chaque onde parmi une onde sinusoïdale et une onde cosinusoïdale, délivrées par le filtre passe-bas, pour calculer des différences d'amplitude et un décalage, et compenser le signal de sortie sur la base des différences d'amplitude et du décalage; et un dispositif de suivi de phase pour générer un signal de sortie du dispositif de suivi de phase par transmission du signal de sortie du compensateur de signal au filtre passe-bas, et calculer une erreur de phase entre le signal de sortie du compensateur de signal et le signal de sortie du dispositif de suivi de phase pour transmettre l'erreur de phase à un filtre à boucle et à un oscillateur de commande de tension.
