a$.)=$Solve for the output voltage Vo in terms of the input voltage, Vin, and

resistors R$1$ and R$2.$

b$.)=$What is the output voltage, Vo$,$ when Vin $=5$V$,$ Vdd $=3$V$,$ and R$1=$ R$2=$

$1$k$?$

c$.)=$If R$1$ were replaced with a potentiometer that could vary from $0$ to $1$ M$,$

what would changing the potentiometer value do to the output voltage?

d$.)=$Compute output voltage values for a set of R$1$ resistances from $1$ through

$1$M$($logarithmically spaced$)$ and briefly discuss what you notice
