本文指出一种把非自启动计数器变换成自启动计数器的设计方法.它在非自启动计数器的某一级插入反馈网络,再根据加入反馈网络后的状态转换图、态序表,求得反馈函数与逻辑方程.这种设计方法准确、简捷、可靠,所得电路简单,而从冗余状态回复到有效状态速度最快.文中结合典型实例进行阐述. This paper points out a non-self-starting counter into a self-starting counter design method. It non-self-starting counter at a certain level into the feedback network, and then join the feedback network after the state transition diagram, Function and logic equation.This design method is accurate, simple and reliable, the resulting circuit is simple, and from the redundant state back to the effective state of the fastest speed.This paper describes a typical example.
