Electronics/Combination gates

Complement of Basic Logic gatesEdit

Basic Gates Combination Gates Symbol Mathematical Expression
BUFFER       Y = is NOT NOT A
Y = A
NOT       Y = is NOT A
NAND       Y = NOT A AND B
NOR       Y = NOT A OR B
XNOR       Y = NOT A NOR B

Truth table of the combination gates

A B Q = A Q = NOT A Q = A NAND B Q = A NOR B Q = A XOR B

(A AND B) OR (A OR B) = A XOR B
(A.B) + (A+B) = A+B
