Q145 / 160 · WBJEE 2015 · Physics
The inputs to the digital circuit are as shown below. The output $Y$ is
- A$A+B+\bar{C}$
- B$(A+B) \bar{C}$
- Correct answerC$\bar{A}+\bar{B}+\bar{C}$
- D$\bar{A}+\bar{B}+C$
Solution
$$
\begin{aligned}
&\text { The output of digital circuit can be given as, }\\
&Y=\overline{A B}+\bar{C}\\
&\text { It will be same as, } Y=\bar{A}+\bar{B}+\bar{C}
\end{aligned}
$$
Hence, the correct answer is option: 'C'.
