Abstract: |
ACCording to the ealaboration on feedback quesition in majority of textbooks,based on many years teaching experience,the author proposes teaching ideas on the important concepts such as general expression of feedback,the definition of feedback polarity,self-excited oscillation and so on from their textbook arrangement and contents combination,and gives expalnations to these important concepts... |
