摘要

本文提出了一种设计近似线性相位IIR滤波器的新方法。该方法首先设计一个近似线性相位的非对称FIR滤波器，然后利用模型约简技术推导出一个低阶近似线性相位的FIR滤波器。

Design of low order approximately linear phase IIR filters

In this paper, a new method for the design of approximately linear phase IIR filters is proposed. This method is based on first designing an asymmetrical FIR filter which is approximately linear phase and then deriving a low order approximately linear phase IIR filter by model reduction techniques.
