Lecture 4 Introduction to Boolean Algebra

Binary Operators In the following descriptions, we will let A and B be Boolean variables and define a set of binary operators on them. The term binary in this case does not refer to base-two arithmetic but rather to the fact that the operators act on two operands. unary operator NOT binary operators AND, OR, NAND, XOR
