Question 57: Semiconductors and Logic Gates

Question

The logic operations performed by the given digital circuit is equivalent to:

Accepted Answer

$$
\begin{aligned}
Z  =\overline{(A+B) \cdot(A \cdot B)} \\
Y  =\bar{Z}=(A+B) \cdot(A \cdot B) \\
\end{aligned}
$$
$$
Y=A \cdot(A B)+B \cdot(A B)
$$
$$
\begin{aligned}
& =A B+A B \\
& =(A B)
\end{aligned}
$$
