Question

The logic circuit shown below has the input waveforms $\text{A}$ and $\text{B}$ as shown in the figure. Pick the correct output waveform

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

Let's make a truth table for the given $\text{NOR}$ gate,

$\begin{array}{ccc}\text{A}& \text{B}& \text{Y}=\overline{A+B}\\ 1& 1& 1\\ 0& 0& 0\\ 0& 1& 0\\ 1& 0& 0\end{array}$

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Hence, $\left(A\right)$ is the correct answer.
