摘要
用一个 84 2 1BCD码表示的十进制异步减法计数器的实例 ,说明各触发器状态方程的表达式 ,并用状态表。
State equations express of Flip-flop are explained by an example of 8421BCD on an asynchronous decimal system decreasing counter. In addition,the logical function of the sequence circuit is demonstrated through state turnover map & state turnover table.
