Abstract: In this paper bandpass filter has been designed and simulated using different windows techniques. Blackman, Hamming and Kaiser Windows techniques are used for design of bandpass filters using matlabs. The performances of all designs have been compared in terms of sidelobe attenuation and mainlobe width. The simulated result shows that Blackman window gives maximum mainlobe width as compared to Hamming and Kaiser Windows. The result also shows that increasing the Kaiser Window parameter Beta widens the mainlobe and decreases the amplitude of sidelobes.
