Q.
What is the output of the combination of the gates shown in the figure?
A) $A + \overline{A \bullet B}$
B) $(A + B) + (\overline{A} \bullet \overline{B})$
C) $(A + B) \bullet (\overline{A \bullet B})$
D) $(A + B) \bullet (\overline{A} + \overline{B})$
Explanation
(a) The input of OR gate is $A$ and $\overline{(A \bullet B)}$. Hence $Y = A + \overline{(A \bullet B)}.$
