三值互斥變量函數(shù)的圖形表示與化簡方法的研究
Research on Mapping and Simplification of Ternary Function with Mutually Exclusive Variables
-
摘要: 該文分析了三值互斥變量的約束條件,提出一種三值互斥變量的圖形表示方法和圖形化簡規(guī)則,大大壓縮了卡諾圖的規(guī)模,把變量的互斥性直觀地表現(xiàn)出來,化簡直觀方便。

Abstract: This paper analyzes the restrictive conditions, proposes a mapping of ternary function with mutually exclusive variables and the graphic simplification rules. It can greatly reduce the size of K-map, and has several advantages such as intuition, convenience easily operating on computers. -
