最大项展开式与COD展开式的转换

Transformation between the Maxterm Expansion and COD Expansion of Logical Functions

讨论了逻辑函数最大项展开式和COD展开式的矩阵转换方法,分析了K图和gj图之间转换的图形方法。在此基础上提出了最大项展开系数和除—符合展开系数转换的表格方法。与图形方法相比,表格方法具有不受变量数目约束,易于计算机的实现等优点。具有较好的实用性。

The matrix transform method between the maxterm expansion and COD expansion for logical function were discussed and the graphic method of the conversion from K map to gj map was analyzed.Based upon it ,a tabular method between the maxterm expansion coefficients and the division-coincidence expansion coefficients was presented,In comparison with the graphic method,this tabular method has several advantages such as without the restriction of the number of variables ,and to be suited to programming on computers ,which is quite practicable.
