Logic Gates - DE

Introduction to Logic Gates

Logic gates are the building blocks of digital circuits. These gates perform basic logical operations on one or more binary inputs to generate a binary output. The primary logic gates include AND, OR, NOT, NAND, NOR, XOR, and XNOR gates.

They are used in various electronic devices like computers, smartphones, and digital watches for performing logical operations in circuits and decision-making systems.

Types of Logic Gates

AND Gate

AND Gate

The AND gate produces a 1 output only if both inputs are 1.

OR Gate

OR Gate

The OR gate produces a 1 output if either of the inputs is 1.

NOT Gate

NOT Gate

The NOT gate produces the inverse of the input.

NAND Gate

NAND Gate

The NAND gate produces a 1 output unless both inputs are 1.

NOR Gate

NOR Gate

The NOR gate produces a 1 output only if both inputs are 0.

XOR Gate

XOR Gate

The XOR gate produces a 1 output if the inputs are different.

XNOR Gate

XNOR Gate

The XNOR gate produces a 1 output if both inputs are the same.

Applications of Logic Gates

Logic gates are used in a variety of applications in digital electronics, such as:

  • Designing digital circuits such as adders and multiplexers.
  • Used in computer processors for arithmetic and logic operations.
  • Forming memory cells in registers and flip-flops.
  • Creating control systems for devices like computers and smartphones.
