# Electronics/Combination gates

## Complement of Basic Logic gates

editBasic Gates Combination Gates Symbol Mathematical Expression BUFFER Y = is NOT NOT A

Y = ANOT 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 0 0 0 1 1 0 0 0 1 0 1 1 0 1 1 0 1 0 1 0 1 1 1 1 0 0 1 0

## XOR

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