Performance analysis of Kaiser-Hamming window for nonrecursive digital filter design

In this study, a new window obtained by the combination of two windows, known as Kaiser and Hamming, is proposed for the design of nonrecursive digital filters. First, the proposed window is analyzed in terms of window spectral parameters and then comparisons with the Kaiser and Hamming windows are performed. The simulation results show that the proposed window can provide better ripple ratio. Moreover, filter comparision results show that the filters designed by the proposed window can provide better minimum stopband attenuation than the ones designed by the Kaiser, Hamming and Chebyshev windows.
