ABSTRACT:
An electrical signal filter for processing a discrete-time real signal having a length N. In one embodiment, the filter comprising a delay line having N taps and a corresponding respective N filter coefficients. Values for the filter coefficients are determined by first shifting an impulse function of length N by a fraction of N so as to obtain a shifted impulse function. An analytic-signal-generating method is then applied to the impulse function so as to output the filter coefficient values. The values are then assigned to the N taps to complete the filter.
