放大电路交流负载线的作法

The Drawing of AC Load Line in Amplificatory Circuit

用图解法对放大电路进行动态分析的目的是观察其工作情况,研究其非线性失真问题。求得 最大不失真输出幅度。分析的对象是交流通路,用图解法进行动态分析的关键是作交流负载线.对交 流负载线的概念、方程、作法作了探讨。

The aim for the dynamic analysis of amplicatory circuit by diagrammatizing is to observe the working state of amplicatory circuit, study its nonlinear distoration and cipher out maximal output range of non-distoration.The analysed object is alternating current(AC) access. The most crucial point to the dynamic analysis is the drawing of alternating current load line. A brief discussion is made in this paper on the concept, equation and drawing of alternating current load line.
