| Abstract: | The K-map and reduced-dimension K-map of a logic function were analysed, based on which, the graphic methods calculating first-order and second-order Boolean E-derivative by using K-map and reduced-dimension K-map according to the definition of logic functions are proposed. The examples show that this method has the features of intuition and simplicity, and it can also obtain the simplest AND/OR expression of Boolean E-derivative. |
