Question

The input to the digital circuit are as shown below. The output Y is:

• A. $A+B+\overline{C}$
• B. $(A+B)\overline{C}$
• C. $\overline{A}+\overline{B}+\overline{C}$
• D. $\overline{A}+\overline{B}+C$

Answer 1

The correct option is C $\overline{A}+\overline{B}+\overline{C}$

The output of digital circuit can be given as, $T=\overline{AB}+\overline{C}$
It will be same as, $Y=\overline{A}+\overline{B}+\overline{C}$
