摘要
数字滤波作为数字信号处理技术的重要组成部分,广泛应用于信号分离、恢复、整形等场合。FIR滤波器因其严格的线性相位特性而应用广泛,通过系统研究数字滤波器的基本理论及基于FPGA的实现方法,给出利用MATLAB仿真软件设计出符合要求的数字滤波器并对其进行仿真验证。
The digital filter is an important part of digital signal processing and is widely used in variety of application such as signal separation,restoration or shaping.FIR filter is widely used because of its strict phase distortion and sharp cut-off characteristic.The basic theory of digital fihcr and the method of realization are researched.The design of the required digital filter is given using the simulate software of MATLAB.and the simulate result is given.
