Improved design of FIR notch filter by using Bernstein polynomial
Chien‐Cheng Tseng · International Journal of Circuit Theory and Applications · 2001
Abstract Bernstein polynomial has been used to design maximally flat FIR notch filters. However, the designed magnitude response is not exactly zero valued at notch frequency. In order to eliminate this undesired distortion, a novel method is presented to improve notch filter design in this paper. The designed notch filter is not only exactly zero valued at notch frequency but also has unity gain at ω=0 and π. Copyright © 2001 John Wiley & Sons, Ltd.
