Logic gates are electronic components that perform basic logical operations like AND, OR, and NOT using binary inputs (0 and 1) to produce a single output.
Introduction To LogicGates
Logics Gates are the building blocks of digital circuit.
They performed basic logical function on binary inputs
(0 and 1).

Basic Logic Gates
1.AND GATE:
Symbol:D-Shape with two inputs and one
output.
Output is 1 only if both inputs are 1.
Boolean expression :A.B
5.
2. OR GATE
Symbol:curved shape with two inputs and one
inputs
Output is 1 if at least one input is 1.
Boolean expression : A.B
6.
3. NOT GATE
Symbol: Triangle with a circle at the tip.
Has one input and one output.
Output is opposite of the input.
Boolean Expression: AorA`
7.
Universal Gates
1. NANDGates:
Combination of AND + NOT
Output is 1 if inputs are different.
Boolean Expression: ~(A.B)
8.
2. NOR Gate
Combination of OR +NOT.
Output is 1 if both are 0.
Boolean Expression: ~(A+B)
9.
Exclusive Gate
1. XORGate(Exclusive OR ):
Output is 1 if inputs are different.
Boolean Expression:A B
⊕
10.
2. XNOR (ExclusiveNOR ) Gate
Output is 1 if inputs are the same.
Boolean Expression:~A B
⊕
