FIR Filter Design based on All Phase Symmetric Frequency Sampling Method


All phase symmetric frequency sampling method is put forward in this paper, which can setup shift variable according to the cut-off frequency. This method exerts inverse phase-shifts on two sub-filters, constructs a compensation filter, and at last combines sub-filters with compensation filter to form the needed low-pass, band-pass filter and notch filter… (More)
