摘要：
A new procedure for designing digital FIR notch filters for a specified notch frequency omega(d) and 3-dB rejection bandwidth DELTAomegaBAR 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.
