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 Logic circuit: AND gate:the circuit which performs AND operation( in simple language multiplication operation
