摘　　要：分析和讨论了基于全状态图的多值移位型计数器的设计方法,指出了当将该方法用于更多值的移位型计数器的设计时,将变得非常复杂,失去了直观性和方便性的特点.提出了多值全状态表及基于全状态表的多值移位型计数器设计方法.此方法能解决上述问题,并给出了二变量四值移位型计数器的设计实例.The design method of multivalued shift-register type counter based on all state map is analyzed and discussed, and then it is pointed out that the number of states for multivalued multi-variable shift-register type counters will increase rapidly with the increment of the radix of the multivaued logic, which makes the multivalued all state very complicated, thus leading to the loss of the features such as intuition and convenience. To overcome this disadvantage the multivalued all state table is presented and a practical example of two-variable quaternary shift-register type counter is given.
