数字电路触发器应用分析——以智力竞赛抢答器设计为例

摘要

In the digital circuit, the trigger is a kind of basic logic memory unit, it has two kinds of logic state,that is 0 and 1, namely no electricity or electric. The trigger circuit has the following function such as recovery function, shielding function, memory function, memory signal function is most important, this is also the most basic logic unit which constitutes a sequential circuit. In order to further application analysis for the digital circuit trigger, taking the quizzes responder design as an example, trigger function and application of the responder circuit were known and studied.%　　在数字电路中,触发器是一种基本的逻辑记忆单元,具有的两种逻辑状态分别为0和1,即通常所说的没电或有电。电路中的触发器所具备的功能主要有三种,包括恢复功能、屏蔽功能、记忆功能,其中最为重要的是记忆信号功能,这也是构成时序电路最为基本的逻辑单元。为了进一步对数字电路触发器的应用进行分析,文章以智力竞赛抢答器设计为例,对抢答器电路中的触发器功能及运用进行了认识和探究。
