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
Introduction to Logic Gates | NOT, AND, NAND, OR, NOR
Logic gates are the heart of digital electronics. A gate is an electronic device which is used to compute a function on a two valued signal. Logic gates are the basic building block of digital circuits. Basically, all logic gates have one output and two inputs. Some logic gates like NOT gate or Inverter has only one … See more
