| 摘 要： | 尽管窗函数法与频率抽样法在FIR数字滤波器的设计中有着广泛的应用,但两者都不是最优化的设计。介绍了一种基于等波纹切比雪夫逼近准则的FIR数字滤波器的最优化设计方法,通过MATLAB的仿真实现,证明了该方法是一种最优化的设计。

| Abstract: | Although window function method and frequency sampling method are widely applied to the design of FIR DF, an optimum design of FIR DF can't be obtained by these two methods. In this paper,an optimum design method of FIR DF based on equivalent ripple Chebyshev approximation rule is introduced. It was proved to be an optimum design method by simulation implementing based on MATLAB. |
