内模型法-
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 .
