Abstract: A method for processing a signal to extract a useful signal from a disturbed signal P1 if the disturbed signal P1 is formed as a sum of a sinusoidal component S1 and an additional component X1. The useful signal corresponds to one of these components. Values of the disturbed signal P1 at three successive times t1, t2 and t3 are determined. Values at the three times t1, t2 and t3 are determined of a signal P2 having a sinusoidal component Sa of the same amplitude as the sinusoidal component S1 and in phase quadrature with respect to the sinusoidal component S1. A value of the useful signal at time t3 based on the values of the disturbed signal P1 and the values of the signal P2 at the three successive times t1, t2 and t3 is calculated.
