| Abstract: | The problem existing in the graphic methods of calculating Boolean difference and partial derivative was analyzed . Based on the definitions of Boolean difference and partial derivative of logical functions , the tabular method calculating Boolean difference and partial derivative was presented. The analyzation showed that the tabular methods proposed in the paper have several advantages such as no drawing , easy operation, and to be suited to programming on computers. |
