Design and Simulation of FIR Digital Filter Based on Matlab

Abstract

The paper analyzed principle of FIR digital filter and introduced implementation process of designing FIR digital filter with Window function method. Matlab simulation verified that parameters of designed filter can be adjusted according to repuirment to achieve desired filtering function. The design is simple and convenient, and has strong applicability.
