| Abstract: | To simplify the process for calculating c-derivative of Boolean function with don't-care-terms in the Boolean logic algebra system based on AND-OR-NOT operation, the K-map method for calculating the first and second-order c-derivative of Boolean function with don't-care-terms is proposed according to the definition of c-derivative. The c-derivative is calculated by folding the square corresponds of the K-map, and then conducts OR operation. The application results show that the presented method is simple and convenient for operation. The simplest AND/OR expansion of c-derivative of Boolean function with don't-care-terms can also be obtained from K-map. |
