A new method for designing IIR multiple notch filters is presented, which satisfies the notch frequency specifications exactly and realizes 3 dB rejection bandwidths which are lower than those specified. An allpass filter-based realization has been worked out to make the design relatively insensitive to coefficient inaccuracies. Illustrative examples are given.
