Q143 / 200 · NEET 2007 · Physics

In the following circuit, the output $\mathrm{Y}$ for all possible inputs $\mathrm{A}$ and $\mathrm{B}$ is expressed by the truth table. Figure

  • A
    Figure
  • B
    Figure
  • Correct answer
    C
    Figure
  • D
    Figure

Solution

Figure \(Y^{\prime}=\overline{A+B} . \quad Y=\overline{\overline{A+B}}=A+B\) Truth table of the given circuit is given by \(\begin{array}{|c|c|c|c|} \hline A & B & Y^{\prime} & Y \\ \hline 0 & 0 & 1 & 0 \\ \hline 0 & 1 & 0 & 1 \\ \hline 1 & 0 & 0 & 1 \\ \hline 1 & 1 & 0 & 1 \\ \hline \end{array}\)

Hence, the correct answer is option: 'C'.
