Question $3$: $(2$ marks$)$

Consider the following $4-$inputs $($A: LSB$,$ and D: MSB$)$ logic function F:

$F\frac{?}{b}=ar\frac{A}{b}ar\frac{B}{b}ar(C)+\frac{A}{b}ar(B)D+A\frac{B}{b}ar(D)\frac{+}{b}ar\frac{A}{b}ar(B)CD$

Implement the function $($connections on the circuit $1$ bellow$)$ by using the multiplexer $(\frac{8}{1}$ : $74151).$ Use the high$-$activated output $y$ of the multiplexer $(F=y).$

Implement the function $($connections on circuit $2$ bellow$)$ by using the demultiplexer$/$decoder $74154($used as decoder $4/16).$
