Question

The output $Y$ of the logic circuit shown in figure is best represented as

$\overline{A} + \overline{B.C}$

$A + \overline{B}.C$

$\overline{A + B. C }$

$\overline{A + \overline{B } .C }$

Answer

$\overline{A + \overline{B } .C }$

Explanation

Solution

At logic gate-l, the Boolean expression is
$\bar{B} \cdot C=Y'$
At logic gate-II, the Boolean expression is
$A+(\bar{B} \cdot \bar{C})=Y''$
At logic gate-III, the Boolean expression is
$\overline{A+\bar{B} \cdot C}=Y$
