| Abstract: | This paper discusses the definitions of Boolean subtraction and division, and the expansions of logic functions in Boolean subtraction- NOT and division- NOT complete sets. The simplification formulas for the above logic functions are given, based on which, the algebraic and graphic simplification methods for the subtraction- NOT and division- NOT logic functions are proposed, and several simplification examples are given. These practical examples prove the effectiveness of the above simplification methods. |
