摘要
针对移位型计数器存在状态利用不足这一问题提出了全状态移位计数器从四位扭环移位计数器状态图中两个有效循环出发分析了四位全状态移位计数器的设计通过讨论拆环链合形成具有移位转换规律的完全状态图得到四位全状态移位计数器反馈函数卡诺图以及反馈函数表达式并给出了任意位全状态移位计数器反馈函数一般表达式
The article puts forward full state shifted counter according to the state抯 using shortage of the shifted counter. It introduces the design of full state shifted counter. Sametime the article analyses the two effective cycles of the 4 bits twisted ring counter抯 state diagram. Then it discusses taken apart ring, chain of ring and the forming of full state抯 state diagram with the shifted regular. And it gets feedback function Karnaugh map and feedback function expression of full state shifted counter. Finally it gives the normal expression of the full state shifted counter抯 feedback function.
