Logic Gates

Which one of the following will be the output of the given circuit?

Show answer and solution

Answer: (a)

AND then NOT: $\overline{AB}$ . OR gate: $A + B$ .
$Y = \overline{AB}\,(A + B) = (\bar{A} + \bar{B})(A + B) = A\bar{B} + \bar{A}B$ .
This is the XOR function.
So the answer is (a) XOR gate.
