Logic Gates, Symbol, Table, explanation, logic

The logic gates are used to build digital cir

cuits. In fact digital circuits are build by logic gates. They are the main parts of digital circuits. Most of the logic gates have two inputs and one output. They are use to do switching in circuits.

There are basics seven types of logic gates.
1. AND gate
2. OR gate
3. NAND gate
4. NOR gate
5. XOR gate
6. XNOR gate
7. NOT gate

Now below is the symbol, logic table and some explanation of all above listed logic gates.
