On the basis of the ordinary design method of synchronous counter and linking laws of synchronous binary counters, this paper gives a simpler and more direct modification method for optimization of the design of module-N synchronous counter, and elaborates the application of the modification method. 在同步计数器的一般设计方法和同步二进制计数器的连接规律的基础上,提出更简捷、迅速、方便的利用修改法优化设计任意进制同步计数器,并做了举例说明。
