Design and realization of FIR digital filters based on MATLAB

Digital filtering occupies an extremely important position in the digital signal processing. This paper introduces the definition and basic principles of FIR digital filters, and the design methods based on MATLAB. After the description of the process of design and simulation of a FIR band-pass filter by means of window function method, the results prove that various performance of the designed FIR filter reach the appointed requirement, the designed method is simple, the design process is handy and efficient.
