自启动是时序逻辑电路设计教学过程中必须考虑的问题,也是数字电路课程教学的重点和难点内容.本文详细介绍了电路不能自启动的原因,并举例说明在时序电路设计教学中,可基于次态卡诺图化简,预先设计好无效状态的次态,实现逻辑电路的自启动.结合卡诺图的方法,使学生更易于掌握时序逻辑电路的设计以及解决自启动问题.
自啟動是時序邏輯電路設計教學過程中必鬚攷慮的問題,也是數字電路課程教學的重點和難點內容.本文詳細介紹瞭電路不能自啟動的原因,併舉例說明在時序電路設計教學中,可基于次態卡諾圖化簡,預先設計好無效狀態的次態,實現邏輯電路的自啟動.結閤卡諾圖的方法,使學生更易于掌握時序邏輯電路的設計以及解決自啟動問題.

@@@@Self -starting, which is the focus and difficult content of digital circuit teaching, must be considered during the course of sequential logic circuit design.We explicitly introduce the reason why the circuit can’t self -start, and provide an exam-ple of how the self -starting may be realized.Based on the secondary state Karnaugh, the secondary state of the invalid state can be appointed in advance to realize the self -starting.It makes students master the design of sequential logic circuit and solve the problem of self -starting in the basis of the secondary state Karnaugh easily.
