关于放大电路反馈类型判别的方法探究

放大电路是模拟电子技术学习的一个重要模块,其中关于反馈类型的判别问题,传统的方法步骤繁多,概念易混淆,很多教材和参考书都没有给出一个清晰、简便的方法,教学过程当中老师也很难给学生讲解清楚,往往只讲负反馈的分类,判别方法一带而过,经过不断地探究和与专家的交流,总结出一套完整的判别负反馈类型判别的新方法,并与传统方法进行比对,讲此方法用于教学实践中,收到了良好的效果。

The amplifying circuit is analog electronics technology learning an important module, wherein the feedback on judging the types of problems, the traditional method of many steps, concepts easily confused, a lot of textbooks and reference books are not given a clear, simple method, the teaching process the teacher is also very difficult to explain clearly to the students, often only negative feedback classification, discriminant method pass, through continuous research and the exchange of experts, summed up a complete set of discriminant methods of judging the types of negative feedback, and traditional methods are compared, this method is used in the teaching practice, has received the good effect.
