Suppose we have a 2input gate with inputs labeled A and B If

Suppose we have a 2-input gate, with inputs labeled A and B. If A and B are both 0, the output is 0. If A is 0 and B is 1, the output is 1. If A is 1 and B is 0, the output is 1. If A is 1 and B is 1, the output is 0. Which gate is this?

Solution

It is an xor gate

Formula for xor operation :A xor B=AB\'+A\'B

   i.e

A B OUTPUT

0 0 0

0 1 1

1 0 1

1 1 0
