同步计数器修正法设计

用修正法设计任意进制同步计数器是在同步二进制计数器高低位触发器连接具有规律的基础上,改变其中某些位的驱动方程,使之按N进制计数器状态计数.修正法较常规用卡诺图化简——求状态方程——求驱动方程的方法,工作效率大为提高,省去了大量重复的卡诺图化简及繁琐的状态方程,避免人为因素造成的差错.

Design of Base N synchronous Counter Usingthe Revised Method

To design base N synchronous counter using the revised method is hased on thatthe connection of the high and low bit of synchronous binary counter is regulour and revisethe drive equation of some bits and make it count in accordomce with the status of the N basecounter. Comparing with the normal method that uses karnaugh map to simplith-get statusequation - get drive equation, this method has high efficiency and many repetivesimplitication of karnough map Can be mited. It's a quick efficient and dandy design methed.
