The Design and Imitate of FIR Digital Filter Based on MATLAB

Jinqiu Zhou

Abstract

Digital filter is the basic components of digital signal processing, the design of it has an important meaning for the digital signal processing. This paper proposes the method of using window function to design FIR filter based on MATLAB, according to the design basic principle of FIR digital filter. In the paper, the simulation result shows that the designed filter can meet the requirements very well and the design procedure is simple and practical.
