Q.
The output $Y$ of the logic circuit shown in figure is best represented as
UP CPMTUP CPMT 2014
Solution:
At logic gate $I$, the Boolean expression is
$\bar {B} \cdot C = Y'$
At logic gate $II$, the Boolean expression is
$A + (\bar{B} \cdot C) = Y''$
At logic gate $III$, the Boolean expression is
$ \overline{A+\left(\bar{B\cdot C}\right)} = Y$
