Digital Logic Gates

This document discusses Boolean algebra and digital logic gates. It introduces Boolean algebra, which uses logical variables and operations like AND, OR, and NOT. These operations are represented with symbols and defined through truth tables. Different types of logic gates are also introduced, including AND, OR, NAND, NOR and XOR gates. The gates are the basic building blocks of digital circuits and are used to implement Boolean logic functions. Functionally complete sets of gates are identified that allow any Boolean function to be implemented.
