As can be seen by the truth table the select lines determine which input is passed through the MUX

and outputted. As such, the number of inputs determines the number of select lines that are needed.

For this task you are asloed to consider the following $4-$variable Boolean function:

$f(w,x,y,z)=2w+x^{\text{'}}y+y^{\text{'}}w+x^{\text{'}}z$

$1.)$ Show the realization of the futction using a $16-1$ MUX. $($Show all your work including your initial

truth table. $)$

$2.)$ It is porsible to also implement this function uning an B$-1$ MUX. Show one way it can be done $($there

are $4$ ways it can be done.$)$
