Logic gates are the fundamental building blocks of digital circuits and systems. They perform logical operations on one or more binary inputs to produce a single binary output. These gates are essential in the design and functioning of digital devices such as computers, smartphones, and microcontrollers12.
Types of Logic Gates
Basic Logic Gates
AND Gate: Produces a high output (1) only when all its inputs are high (1). The Boolean expression for a two-input AND gate is ( Z = A \cdot B ). A | B | A AND B --|---|-------- 0 | 0 | 0 0 | 1 | 0 1 | 0 | 0 1 | 1 | 1
OR Gate: Produces a high output (1) if at least one of its inputs is high (1). The Boolean expression for a two-input OR gate is ( Z = A + B ). A | B | A OR B --|---|------- 0 | 0 | 0 0 | 1 | 1 1 | 0 | 1 1 | 1 | 1
NOT Gate: Produces an output that is the inverse of the input. The Boolean expression for a NOT gate is ( Z = \overline{A} ). A | NOT A --|------ 0 | 1 1 | 0
