2.2 Basic Operations AND, OR, NOT(complement) Switch can be used to illustrate concept. –Open switch is a 0. –Closed switch is a 1. –Picture of gate representations and truth table descriptions are illustrated on page 38 and 39.

Boolean Expressions and Truth Tables Expressions are illustrated by 2-1 and 2-2, page 39 and the resulting gate diagrams are at the top of page 40 in Figure 2-1. Figure 2-2 and Table 2.1 illustrate Truth Tables. (two input an three input tables)

2.4 Basic Theorems X+ 0 = X X+ 1 = 1 Duality equations are : –X and 1 = X –X and 0 = 0
