Q.
The output $Y$ of the logic circuit shown in figure is best represented as
A) $\overline{A} + \overline{B \bullet C}$
B) $A + \overline{B} \bullet C$
C) $\overline{A + B \bullet C}$
D) $\overline{A + \overline{B} \bullet C}$
Explanation
(d) At logic gate$\ I$, the Boolean expression is $\overline{B} \bullet C = Y^{'}$
At logic gate II, the Boolean expression is $A + \left( \overline{B} \bullet C \right) = Y^{''}$
At logic gate III, the Boolean expression is $\overline{A + (\overline{B} \bullet C)} = Y$
