【摘要】 和同步计数器相比,异步计数器的设计面临2个突出的难点:一个是各触发器时钟信号的选取,一个是从状态转换图化简整理各触发器的状态方程时卡诺图的正确获取.对此进行了分析并提出了具体的解决方法.更多还原

【Abstract】 Compared with the synchronized counter,the asynchronous counter faced two prominent difficult questions in design: One is the selection of clock signals of various triggers,the other is the correct gain of the karnaugh map at the time when the is simplified into the equation of state for varions triggers.After careful analyses,concrete solution are presented.更多还原
