Suppose we have ${1111111111101001}_2.$

$4\mathrm{.}1.(5$ points$)$ Suppose the binary number is in $16-$bit $2\text{'}$s complement format.

Decode the binary number into a base$-10$ number. Note that MSB is used for

sign.

$4\mathrm{.}2.(5$ points$)$ Suppose the binary number is in $16-$bit unsigned value format. Decode

the binary number into a base$-10$ number.
