Method of eliminating a DC component and filtering device obtained by this method

The present invention relates to a method of eliminating a DC component from an electronic signal, comprising: making a configuration of a filter so that it has a transfer characteristic that offers at least a zero at a predetermined frequency, called cut-off frequency, providing a shift of said transfer characteristic, the extent of which shift is equal to the absolute value of the cut-off frequency, causing said electronic signal to flow through the filter thus obtained. A filtering device obtained by such a method is easily integrable and offers little time-dependent inertia.
