Topic: Digital Circuits
Following circuit implements a (Circuit with inputs $A_0$, $A_1$, $I_0$, an inverter on $I_0$, two AND gates, and an OR gate giving output Y)
- A. De-Multiplexer
- B. Multiplexer
- C. $Y = I_0(A_0 + A_1)$
- D. $Y = I_0(\overline{A}_1 + A_0)$
Answer: B. Multiplexer
Explanation: The output of the logic circuit can be written as $Y = A_0I_0 + A_1\overline{I}_0$. This is the standard boolean expression for a $2 \times 1$ Multiplexer where $I_0$ acts as the select line choosing between inputs $A_0$ and $A_1$.
