四值互斥变量K图及其化简

Quaternary K-map for mutually exclusive variables and its simplification.

参照二值互斥变量K图的讨论,提出了四值互斥变量K图,讨论了它的特点以及在四值互斥变量逻辑函数化简中的应用,给出了四值互斥变量K图化简的规则,并用具体实例作了说明.提出的四值互斥变量K图大大地压缩了K图的规模。

Based on the discussion of binary K-map for mutually exclusive variables, this paper proposes quaternary K-map for mutually exclusive variables, discusses its features and its application in the simplification of quaternary logic functions with mutually exclusive variables and gives out the simplification rules of quaternary K-map for mutually exclusive variables and several practical examples. The quaternary K-map for mutually exclusive variables presented here greatly reduces the size of K-map, thus expanding the application range of K-map.
