| Abstract: | A new procedure for designing digital FIR notch filters for a specified notch frequency ωd and 3-dB rejection bandwidth Δω has been proposed. Design formulae for computing the required weights and the length N for the filter have been derived. Illustrative examples confirming the new approach are also given |
