Abstract
This electronic notch filter is able to receive an input signal and deliver a filtered signal having an amplitude, at a cut-off frequency, that is attenuated with respect to that of the input signal. It comprises a module for integrating the input signal during several successive time windows, each time window starting at a respective initial time instant and having a duration substantially equal to the inverse of the cut-off frequency, the initial temporal time instants of at least two distinct windows being separated by a temporal shift of a value greater than or equal to a predefined reference duration, each integration of the input signal during a respective temporal window resulting in a respective intermediate signal; and a module for summing the intermediate signals coming from the integration module; the filtered signal depending on the sum of said intermediate signals.
