摘要
基于内平衡结构模型压缩法,通过对线性相位FIR滤波器的降阶处理,本文得到了一种稳定的线性相位IIR滤波器的逼近方法,计算机模拟结果证实了本文的理论分析。
Based on the model reduction of internally balanced structure,an approximation method of stable linear phase IIR digital filters is obtained by means of reducing the orders.This theory is verified by computer simulation results.
