判断组合逻辑电路中冒险现象的卡诺余子图法

Karnaugh Complementary Map Procedure Judging Adventure Phenomenon in Combinational Logic Circuit

在组合逻辑电路中,不可避免地会遇到冒险现象。在卡诺图中剔除掉输入信号中不变的变量,构成卡诺余子图。而卡诺余子图法,就是通过观察所得的卡诺余子图是否广义和谐来判断是否存在冒险现象。在卡诺余子图的基础上,提出了避免冒险现象的方法,从而系统化了冒险现象的判断。

We can not avoid Adventure Phenomenon in Combinational Logic Circuit.We get Karnaugh Complementary Map by eliminating changeless.Variable in input signal in Karnaugh Map.And so-called Karnaugh Complementary Map Procedure is a method to judge if there is Adventure Phenomenon in Combinational Logic Circuit by observing if the Karnaugh Complementary Map is harmonious or not.Come up with a way to avoid Adventure Phenomenon based on Karnaugh Complementary Map,therefore,we can judge Adventure Phenomenon systematically.
