Basic Gate 1. AND Gate

1. AND Gate:
          Symbol:
                     

It has two input A and B and has only one output Y=A*B.

Truth Table for Two Input

Input		Output
A	B	Y=A*B
0	0	0
0	1	0
1	0	0
1	1	1

Truth Table for Three Input

Input			Output
A	B	C	Y=A*B
0	0	0	0
0	0	1	0
0	1	0	0
0	1	1	0
1	0	0	0
1	0	1	0
1	1	0	0
1	1	1	1

logic gate

        DEFINATION:- It is an electronic circuit which takes one or more input but produce only one output.

         logic gate has 3 types.

         1) BASIC GATE

             - AND gate

             - OR gate

             - NOT gate.

         2) UNIVERSAL GATE

            - NAND gate

            - NOR gate

         3) EXCLUSIVE GATE

           - EX-OR gate

           - EX-NOR gate

information about all the gates will be in the next post...so keep in touch
