ABSTRACT
This chapter describes the logic gates, such as AND, OR, NOT, NAND, NOR, and XOR. It explores the symbols for the logic gates, the use of logic gates in digital processes, and the use of logic gates with timing diagrams. The chapter explains the logic functions for logic gates and the laws of Boolean algebra for logic circuits. It shows what the product of sums and sum of products are, what their purposes are, what K-maps are, and how they can be used. The chapter explores the use of K-maps to define logic function of practical problems. The Boolean algebra is a set of specific rules that governs the mathematical relationships corresponding to the logic gates and their combinations. Their application is limited to two-valued (0 and 1) entries such as the inputs and outputs of logic gates. Boolean algebra can help to verify and identify the circuits.
