双线性变换中的映射

Reflex in bilinear transformation

设计数字滤波器时,常用到双线性变换法,本文主要分析变换过程中,S 平面到 S_1平面到 Z 平面,三个平面间的映射关系。

To drsign digital filter, the method of Bilinear Transfomtion is often used.This paper mainly analysed analysed reflexions among three places , s-place to s1-place to Z-place in transformation.
