摘要
本文讨论了窗函数法和一种基于切比雪夫等波纹逼近准则的FIR数字滤波器的最优化设计方法。通过MATLAB对这两种FIR数字滤波器的设计结果进行仿真比较,发现在同样阶数下,等波纹优化设计具有通带和阻带平坦,过渡带窄的优点。
According to the basic principle of FIR Filter, two methods to design FIR Filter have been studied by means of mathematical approach based on MATLAB, which is window function and optimal design. By comparing the results of the two design, we find the optimal design based on equivalent ripple Chebyshev approximation rule has a great deal of advantages including smooth pass band and forbidden band, and narrow transition band in the same order.
