Abstract:
1. A method of extraction of at least one sinusoidal component of an input signal, comprising the steps of estimation of the amplitude of said sinusoidal component of said input signal; estimation of the frequency of said sinusoidal component of said input signal; estimation of the total phase of said sinusoidal component of said input signal; synthesization of said sinusoidal component of said input signal; and estimation of an error signal representing the difference between said input signal and said sinusoidal component of said input signal by the use of a first subtraction, wherein: the sinusoidal component of the input signal is the desired component of the input signal to which convergence is sought and specification of which is accomplished by predetermination of its frequency, and the error signal is the totality of the undesired components present in said input signal.
