Design of digital FIR notch filters
S. C. Dutta Roy · IEE Proceedings - Vision Image and Signal Processing · 1994
A new procedure for designing digital FIR notch filters for a specified notch frequency omegad and 3-dB rejection bandwidth Delta omega 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.
