| 摘 要： | 分析了逻辑函数在部分变量取反时的或-符合展开系数图(即dj图)和降维或-符合展开系数图(即降维dj图),在此基础上提出了用dj图和降维dj图计算逻辑函数的一阶布尔差分和二阶布尔差分的图形方法。实例表明,该图形方法有直观、简单等特点。它能给出逻辑函数布尔差分的最简或/符合式。

| Abstract: | The expansion coefficient map(also called dj map)in OR-coincidence system is introduced.And then the dj map and reduced-dimension dj map of a logic function with partial variables negated are discussed.Based on it,a graphic method of calculating first-order and second-order Boolean difference of a logic function by using dj map and reduced-dimension dj map is proposed.The examples prove that this method has the features of intuition and simplicity,by which the simplest OR/COINCIDENCE expression of Boolean difference can be obtained. |
