ABSTRACT: In the field of digital communications, a filter is a device that selectively attenuates any unwanted component of a received signal and essentially changes the signal waveform in the desired manner. In this paper, we study a finite impulse response (FIR) bandpass filter using Hamming and Kaiser window methods and compare them for further analysis using Matlab software. The parameters used for the design of this filter are sampling frequency, cutoff frequency and filter order. This study shows good conformity of these two methods at the passband level and a slight difference at the lower and upper attenuation band level.
