JDP_V4_N2_RP3 Manjinder Kaur Sangeet Pal Kaur Journal on Digital Signal Processing 2322–0368 4 2 17 23 Hanning, Hamming, Blackman Window, FIR Filter, MATLAB R2014a This paper presents a new window for designing FIR low pass filter. While designing a FIR filter, there are two important parameters which must be taken care of which are transition width and ripples. Transition width should be as small as possible and ripples should be less both in pass band as well as stop band. There are different windows like Rectangular, Triangular, Hanning, Hamming, Blackman, etc., which are used for filter designing. The proposed window which is a modified form of Blackman window contains four cosine parameters and the simulation result shows that this window has better response when compared to Blackman Window.
