摘要

采用封闭网络模型

按照电路元件参数

采用开路、短路和着色运算

将电路图逐层分解

得到网络展开图.给出网络展开图的概念和运算规则

指出网络展开图中从根到末稍每个路径的值就是网络行列式展开式中的一个有效项

从而由网络展开图得到符号网络函数.该方法直接对电路图进行运算

不需要建立任何形式的电路方程和行列式

适用于一般的有源电路

而且能生成各种类型的网络函数.

Abstract

Employ the model of closed network

decompose the circuit by opening

shorting and coloring some edges auording to the element parameters

one tier by one tier

then a graph called the Network Expansion Diagram (NED) is built up.The concept and rules of NED are given.It is pointed out that the value of every path in NED just is one valid term of the expanded network determinant.Then the symbolic network functions can be obtained from NED.This method handles directly circuits by graph operations.It is applicable for generating all types of network functions to general active circuits.
