Comb-Based Filter Design Using Sharpening Technique and Certain Palindromic Polynomial
Gordana Jovanović Doleček · Journal of Applied Mathematics and Physics · 2023
This paper presents a novel approach to improve aliasing rejection in comb-based decimation filters. The method is established on certain palindromic polynomials with all zeros on the unit circle and the sharpening technique. As a result, aliasing rejection and the passband characteristic are improved. The method is illustrated with various examples and compared with the methods from the literature.
