摘　　要：时序逻辑电路的设计过程中,电路是否能够自启动是必须考虑的问题,也是数字电子技术课程教学的重点和难点内容。通过详细分析电路不能自启动的原因,提出了利用卡诺图消除不能自启动的问题,修改次态卡诺图,为次态卡诺图中的无效状态指定次态,指定的次态属于有效循环状态。利用该方法实现了逻辑电路的自启动。In the design process of sequential logic circuit, the circuit is the key part of the digital electronic technology course. Through the detailed analysis of the circuit, we prove that using Karnaugh map can＇t eliminate the slef starting problems. Modify the next state Karnaugh map for next state Karnaugh map in the invalid state designated of secondary state, and the designated secondary state belongs to the effective cyclic state. Using this method to achieve logic circuit from the start is proposed at last.
