反馈电路类型的判别分析

Analysis of Distinguishing of Feedback Circuit Types

反馈在电子电路中的应用非常广泛,在电子技术中占有重要地位,正确判断反馈类型非常重要。本文就反馈电路包括直流反馈和交流反馈、正反馈和负反馈、串联反馈和并联反馈、电压反馈和电流反馈类型的判别作了较为深入分析,给出了不同电路反馈类型快速有效的判别方法,并结合图例作以说明。

Feedback is wildly used in electronic circuit applications, which plays an important role in electronic technology. It is very important to distinguish the type of feedback. This paper analyzes profoundly distinguishing of the type of feedback circuit,including negative and positive feedback, the series or parallel feedback, the voltage or current feedback, and recommends some effective methods of how to distinguish the type of feedback different circuits, and illustrates these methods with several examples.
