Abstract: The method includes an adjustment phase in which a filtering device is operated as an oscillator, the frequency of oscillation of the filtering device is determined, and the characteristics of the filtering device are corrected with respect to the determined oscillation frequency and to a pre-established relation between the frequency of oscillation and the theoretical cutoff frequency, in such a way as to confer upon the filtering device a cutoff frequency equal to the theoretical cutoff frequency to within a tolerance. After the adjustment phase, a working phase takes place in which the filtering device carries out its filtering function.
