摘要
特性方程和电压波形图都是触发器重要的逻辑功能表示方法.文中结合具体实例,说明直接根据特性方程画主从触发器电压波形图时会遇到的问题,并结合其电路结构及动作特点给出了解释,指出了特性方程适用的条件,同时也总结出了主从触发器电压波形图的画法.这种提出问题、分析问题并解决问题的教学方法可以提高学生的学习兴趣并加深对内容的理解,提高教学质量.
The formula and the voltage-waveform diagram are two important ways to describe flip-flop circuits. In this paper, the problem is discussed when we draw voltage-waveform diagrams according to the formula. The explanation is given by means of analyzing the circuit structures and running characters, and at the same time, the proper use condition of the formula is obtained. A set of ways of drawing voltage-waveform diagrams is summarized to the master-slave flip-flop circuits, consequently a teaching way to deal with the content of the master-slave flip-flop is given.
