Analytical design of maximally flat notch FIR filters for communication purposes

Abstract

A novel fast analytical design procedure for the maximally flat notch FIR filters is introduced. The closed form solution provides recursive evaluation of the impulse response coefficients of the filter. The discrete nature of the notch frequency is emphasized. One design example is included in order to demonstrate the efficiency of the presented approach. © Springer-Verlag Berlin Heidelberg 2005.
