Basic Gates, Universal gates, other gates

AND Gate: the circuit which performs AND operation( in simple language multiplication operation) is called as AND Gate.

AND gate is a circuit that has high output when both inputs are high, otherwise low.

Truth table:

A	B	Output(Y)
0	0	0
0	1	0
1	0	0
1	1	1

Logic Expression:

Y=A AND B AND C....N    (For n inputs)

Y=A .B.C.....N

Y=A AND B      ( for 2 inputs)

Y= A.B

logic circuit:

OR Gate:the circuit which performs OR operation( in simple language addition operation) is called as OR Gate.

OR gate is a circuit that has high output when any one inputs is high, otherwise low.

Truth table:

A	B	Output(Y)
0	0	0
0	1	1
1	0	1
1	1	1

Logic Expression:

Y=A OR B OR C....N    (For n inputs)

Y=A .B.C.....N

Y=A OR B      ( for 2 inputs)

Y= A.B
