Abstract

L’invention concerne un procédé (100)de traitement de signal pour extraire un signal utile d’un signal perturbé P1 dans le cas où le signal perturbé P1 est formé par la somme d’une composante sinusoïdale S1 et d’une composante supplémentaire X1. Le signal utile correspond à l’une de ces composantes. Le procédé comporte : - une détermination (110) de valeurs du signal perturbé P1 en trois instants successifs t1, t2 et t3, - une détermination (120) de valeurs auxdits trois instants t1, t2 et t3 d’un signal P2 comportant une composante sinusoïdale S2 de même amplitude que la composante sinusoïdale S1 et en quadrature de phase par rapport à la composante sinusoïdale S1, - un calcul (130) d’une valeur du signal utile à l’instant t3 en fonction des valeurs du signal perturbé P1 et des valeurs du signal P2 aux trois instants t1, t2 et t3.
