Question

What are the 3 Logical Operators?

Answer 1

Logical operator:

• A binary variable function whose result is likewise a binary variable.
• In digital circuits, logic gates perform logical processes.
• AND, OR, and NOT are examples of logical operations.

Types of logical operators:

• AND gate:
  • The circuit symbol of a two input AND gate is shown in figure given below.
  • A and B are inputs and Y is the output.
  • It is a logic gate and hence A, B, and Y can have the value of either 1 or 0.
  • It is also called Conjunction operator.

• OR gate:
  • The circuit symbol of a two input OR gate is shown in figure given below.
  • A and B are inputs and Y is the output.
  • It is also called Disjunction operator.

• NOT gate:
  • The circuit symbol of NOT gate is shown in figure given below. A is the input and Y is the output.
  • It is also called Negation operator.
