Types of logic gate
(a) AND logic gate
(b) OR logic gate
(c) NOT logic gate
Application of logic gate

3. What is logic gate:-
A logic gate is a basic building block of digital electronics. It is an
electronic circuit that performs a logical operation on one or
more binary inputs (0 or 1) and produces a single binary output.

4. AND Gate:-
Output is 1 only when all inputs are 1.
OR Gate:-
Output is 1 when any one input is 1.
NOT Gate:-
Produces the inverse of the input.
NAND Gate:-
Output is 0 only when all inputs are 1.
Types of logic gate:-
NOR Gate:
Output is 1 only when all inputs are 0.
XOR Gate:-
Output is 1 when inputs are different .
XNOR Gate:-
Output is 1 when inputs are same.

5. Y=A B
⋅
A B Y (A·B)
0 0 0
0 1 0
1 0 0
1 1 1
AND logic gate:-
An AND gate is a basic logic gate that gives output 1 (TRUE) only
when all inputs are 1.
If any input is 0, the output will be 0.
symbol:-
A ──┐
AND ── Output
B ──┘

6. OR logic gate:-
Y=A+B
An OR gate is a basic logic gate that gives output 1 (TRUE) if
any one or more inputs are 1.
The output is 0 only when all inputs are 0.
A B Y (A + B)
0 0 0
0 1 1
1 0 1
1 1 1
symbol:-
A ──┐
OR ── Output
B ──┘

7. A NOT gate is a logic gate that gives the opposite (inverse) of the
input.
Input 1 → Output 0
Input 0 → Output 1
That’s why it is also called an Inverter.
NOT logic gate:-
A Y (NOT A)
0 1
1 0
Y=A or Y=A′
symbol:-
A ──|>o── Y
