Question

For the given circuit, the input digital signals are applied at the terminals $A,B$ and $C$. What would be the output at the terminal $y$?

• A.
• B.
• C.
• D.

Answer 1

The correct option is C


Output at $y=A\cdot B+\overline{B\cdot C}$



So, the output at $y$ is high $\left(1\right)i.e.V_0=5\text{V}$.

Hence, option $\left(\text{C}\right)$ is the correct answer.
