对异步计数器电路设计的讨论

Discussing of the Design of Asynchronous Counter Circuit

本文讨论了在异步计数器的电路设计过程中,当某级电路的时钟CP不满足,求该级电路状态方程时,将此时刻的状态作为任意项处理,从而使设计出的电路达到更简。并以设计8421BCD码十进制计数器为例,说明了设计方法和步骤。

This paper discusses the course in the circuit design of asynchronous counter. On the basis of the above and illustrates the design method and step by designing 8421BCD code decimal for the example.
