摘要
本文探讨了异步计数器设计中确定触发器次态卡诺图的一种新方法一依据时序图确定为0为1最小项法,并以一个异步十进制加法计数器的设计为例,论述了新方法的先进之处.
This paper advances a new methodology to determine the Karnangh Map for the second state of tirggers in the design of asynchronous counters. With an asynchronous decimal counter being taken as an example, the advantages for the new methodology is disscussed.
