利用高斯消去法求无源二端口网络参数

Solving the Parameters of Passive Two-port Network Through Gaussian Elimination Algorithm

历来求无源二端口网络参数，用网络两个端口的开路或短路分别去求出二端口网络的各个参数。求解时对于简单的网络尚可，然而只要网络稍复杂，即难于求解。本文提出一种统一的方法用于求解网络的参数，利用变形后的高斯消去法，对网络解耦，从而求得两端口网络的参数，算法统一，既可用以计算机辅助计算，亦可用于手工计算，方便简捷，尤其是对于Ｙ参数和Ｚ参数。

To solve two-port circuit parameters, the method is making use of short and open the two ports as usual The circuit is more complex,the process is more difficult This paper is to give out a systematic method—making use of reverse Gaussian elimination method to solve two-port parameter, that is much easier than the usual method in computer aided and in manual, special to Y parameter and Z parameter
