Unformatted text preview: kinds of Boolean expressions, rather than arbitrary variables such as D, E, and X. That makes it more clear what each column represents. In fact, we can use Boolean expressions to label our logic diagrams as well, eliminating the need for intermediate variables altogether. Now let’s go the other way; let’s take a Boolean expression and draw the corresponding logic diagram and truth table. Consider the following Boolean expression: A(B + C) In this expression, the OR operation is applied to input values B and C. The result of that operation is used as input, along with A, to an AND operation, producing the final result. The corresponding circuit diagram is therefore: A B C B + C A(B + C) A 1 1 1 1 B 1 1 1 1 C 1 1 1 1 D 1 1 E 1 1 X 1 1 1...
