Filters are widely employed in signal processing and communication systems in applications such as channel equalization, noise reduction, radar, audio processing, video processing, biomedical signal processing, and analysis of economic and financial data. Window methods are prominently used in the design of digital FIR filter. The paper studies the comparative analysis of a proposed high pass FIR filter design using Kaiser, Rectangular and Tukey window methods with the aid of FDATOOL in MATLAB. From the comparative analysis Rectangular is found to be the best for the proposed filter design based on the magnitude responses of the three windows.
