This paper presents a new design method for IIR notch filters with improved performance while operating with a limited number of samples. The design criterion is to minimize the error between the steady state and transient frequency responses while utilizing the initialization technique. The new filters which use multiple frequency initialization offer better transient frequency responses than conventional steady state filters with initialization.

This paper presents a new design method for notch IIR filters. The designed filters offer better transient frequency response for a given number of samples when compared to zero and projection initialization. Fine-tuning the positions of the poles to maximize the 3dB bandwidth of the transient frequency response for a given number of samples achieves the improvement. Second order filters were successfully designed for processing different numbers of samples and their performances were studied by considering their frequency responses.
