放大电路中反馈类型的教学方法探讨

Discussion on the Teaching Method of Feedback Types in the Amplification Circuits

反馈是电子系统的重要组成部分,反馈的内容丰富,教学中涉及的知识点广泛。本文结合具体实例电路,对反馈放大电路中存在的却不常提及的反馈类型提出了分析处理方法,这种教学方法对全面完整地理解反馈的概念行之有效。

Feedback is an essential and important component in the electronic system. The classification of feed- back is content-rich and knowledge points involved in the teaching process is extensive. In this paper, combined with actual circuits, an analytical method is proposed regarding feedback types which are not frequently referred to yet exist in the feedback amplification circuits. This teaching method is proved to be effective in comprehensively understanding the concept of feedback.
