在脉冲数字电路中,触发器的教学是个难点,大多数教材中对双稳态触发器只作一般的电路分析,结果学生头绪混乱,弄不清来龙去脉,学起来很费劲。笔者在严格的逻辑推导基础上进行分析,从比较中勾通各种触发器之间的逻辑关系,教学中收到了满意的效果,现将主要内容介绍如下。 In the pulse digital circuit, the teaching of the trigger is a difficult task. Most of the teaching materials only make a general circuit analysis of the bistable trigger. As a result, the students are confused and can not figure out the whole sequence of circumstances. The author carries on the analysis on the basis of rigorous logical derivation, draws the logical relations among various triggers from the comparison, the teaching has received the satisfactory effect, now the main content is introduced as follows.
