Consider the following logic circuit. The output is Y=0 when :

Consider the following logic circuit.

Consider the following logic circuit. The output is Y=0 when :

The output is

\mathrm{Y}=0

when :

Options

A $\mathrm{A}=1$ and $\mathrm{B}=1$
B $\mathrm{A}=0$ and $\mathrm{B}=1$
C $\mathrm{A}=1$ and $\mathrm{B}=0$
D $\mathrm{A}=0$ and $\mathrm{B}=0$

Correct answer

A. $\mathrm{A}=1$ and $\mathrm{B}=1$

Step-by-step solution

\begin{aligned}& \mathrm{Y}_1=\mathrm{A} \cdot \mathrm{ B}, \mathrm{Y}_2=\overline{\mathrm{A}}+\mathrm{B} \\ & \mathrm{Y}=\overline{\mathrm{Y}_1 \cdot \mathrm{Y}_2}=\overline{\mathrm{Y}_1+\overline{\mathrm{Y}_2 \\ & \mathrm{Y}=\overline{\mathrm{A} \cdot \mathrm{ B}}+\overline{\mathrm{A}+\mathrm{B}} \\ & \mathrm{Y}=\overline{\mathrm{A}}+\overline{\mathrm{B}}+\mathrm{A} \cdot \overline{\mathrm{ B}}\end{aligned}

\begin{array}{|c|c|c|} \hline A & B & Y \\ \hline 0 & 0 & 1 \\ \hline 1 & 0 & 1 \\ \hline 0 & 1 & 1 \\ \hline 1 & 1 & 0 \\ \hline \end{array}
