在电子学的教学中,我们一直把反馈放大器的计算作为反馈一章的基本内容,因为只有掌握了它才能对反馈作定量分析,也才能全面地深入地认识反馈的效果。但它又是难点,难就难在学生不善于对反馈网络作“断环”处理,不理解开环参数的概念,不懂得方块图同具体电路之间的联系。不过,教材写法和教师讲法得当,难点可以克服。通过教学的反复实
In the teaching of electronics, we always use the calculation of feedback amplifier as the basic content of the feedback chapter, because we can only quantitatively analyze the feedback and know the effect of feedback thoroughly and thoroughly. But it is also difficult, difficult to difficult students in the network is not good at “broken ring” for the feedback network, do not understand the concept of open-loop parameters, do not know the block diagram with the specific circuit connection. However, the teaching materials and teachers proper way of writing, the difficulties can be overcome. Through repeated teaching practice
