对共射电路的两点讨论分析

The Analysis of Two Aspects of the Common－ Emitter Circuit

分析了放大管的β值对两种共射电路的静态工作点和电压放大倍数的不同影响，从而得到对输出波形的不同影响.

In this paper,the writer analysed the influence that transistor sβ has on the quiescent point and the voltage gain of two common－ emitter circuits,hence the influence on the output waves.
