摘要
数字滤波器在数字信号处理中有着广泛的应用。它分为有限长脉冲响应(FIR)滤波器和无限长脉冲响应(IIR)滤波器。通过比较,从FIR数字滤波器稳定性和线性相位的特性出发,利用MATLAB实现64阶FIR低通滤波器的设计,并对被高频干扰的信号进行滤波处理,达到预期的实验结果。
Digital filter has a wide range of applications in digital signal processing. It is divided into FIR filter and IIR filter. Through the comparison, FIR digital filters are stability and linear phase, A 64 first-order FIR low-pass filter is designed based on MATLAB, The signal which disturbed by hign frequency is filtered,and it is effective.
