2. Logic Gates
A Logic gate is an electronic cercuit which
makes logical decisions, and perform logical
operation is called logic gates.

3. Type of logic gates
BASIC GATES UNIVERSAL
GATES
1. AND GATE 1. NAND GATE
2. OR GATE 2.
NOR GATE
3. NOT GATE 3. XOR GATE
There are two types of logic gates

4. AND GATE
AND gate perform logical multiplication.
Operation =( A.B )
AND gate have two or more than two input
and one output.

6. OR GATE
OR gate perform logical addition .
Operation = (A+B) .
OR gate have two or more than two input
and one output.

8. NOT GATE
Not gate perform logical complement function.
purpose of Not gate is to convert one logical
operation into its opposite is called NOT GATE.

9. NAND GATE
NAND gate is combination of NOT-AND gate.
I.e. it is complement of AND gate.
It has two or more than two inputs and only
one output.

11. NOR GATE
NOR gate is combination of NOT-OR gate.
i.e. it is complement of OR gate.
It has two or more than two inputs and only
one output.

13. XOR GATE(exlusive-or gate)
XOR gate is a gate with two or more inputs
and one output.
The XOR gate has a high output only when an
odd no. of inputs are high.
