| 摘 要： | 一般情况下,多级放大电路的开环放大倍数都比较高,引入负反馈很容易满足1+AF>>1的条件。这时,放大电路闭环放大倍数的定量计算将变得非常简单:Af=1/F;下面主要分析这种情况下放大电路的定量计算方法和规律。

| Abstract: | On the ordinary situation, the multiple amplification electric circuit open circuit magnification is taller and introducing the negative feedback easily meets the terms of 1 + AF > > 1. Then, ration calculation of the electric closed circuit magnification will become very simple;AF≈1/F;In the paper, the author mainly analyze the rules and methods of the ration calculation of the amplifi-cation electric circuit. |
