Design and implement an $8-$bit multiplexer that passes through one of two $8$ bit inputs to an $8$ bit output.

Inputs: A$7.\mathrm{.}0,$ B$7.\mathrm{.}0$

Control: S$0$

Output: Q$7.\mathrm{.}0$

NOTE:: this circuit should be made entirely of $2-1$MUX's

Explain the circuit in detail. Include why you chose each gate and why it is connected the way it is$.$ Don$$t just describe the circuit, explain why!

Use hex keyboards and hex displays to show the testing of the internal circuit. Explain the input, and why the output is what is expected. You can do this through

an annotated wave from and explain what is happening at each rising edge

through multiple images of the circuit showing the A$\text{'}$s passing through when S$0$ is $1$ and B passing through when S$0$ is $0.$

Package the internal circuit and label it $8$MUX$-2$

replace the input and out devices with Port in and Port out pins first

show the testing of the packaged circuit similarly to the previous step. Although less description is necessary, since it is the same as the previous.
