| 模拟电子技术中的很多基本电路都可视为三端子两端口网络。在学习过程中，为有效分析其输入-输出特性，往往需要对其进行输入回路和输出回路的拆分式解耦等效分析，而阻抗参数等效变换成为一大难点。基于电路理论基础知识，对三端子两端口网络的串联式和并联式阻抗参数等效变换进行了详细推导，并将所提的参数等效变换方法应用于三个典型模拟电路的特性分析，有效简化了电路分析过程。 |
| 英文摘要: |
| Many basic circuits in the analog electronics can be regarded as the two-port network with three terminals, and they need to be decoupled into the input and output loops when their circuit characteristics are analyzed. However, the transformation of the impedance parameters from the original to the decoupled circuits is difficult to understand. This paper derives the parameters transformation of the parallel- or series-connected impedance in the two-port network with three terminals, and employs this method to analyze three typical analog circuits in the textbook. The proposed method can simply the analysis of the analog circuits. |
