FIR Filter Design using an Adjustable Window Function & Justification with Different Windows
In this paper a window function is explained with regulated variable value and the window is
compared with hamming, kaiser, blackman, hanning& another proposed window. Besides FIR filters designed
using the window function & other windows mentioned above, are compared. The result implies that the sidelobe
roll off ratio of the proposed window with regulated variable(0.0009) is 71.76dB where blackman, hanning,
hamming, Kaiser & another proposed windows have 43.22dB, 55.71dB, 7.34dB, 18.96dB, 34.25dB,
respectively while for the proposed window with variable value 0.18 has side-lobe roll off ratio 24.65dB.
