Convert the hexadecimal value E$6.$

a$.$ to $8$ bit binary

b$.$ to decimal $($assume it is a signed value$)$

$3)$ Perform the following binary arithmetic using $6$ bit numbers: $101101+010111.$

Show the decimal values represented by both numbers and sum for unsigned and signed.

a$.$ Assuming the values represent unsigned binary

b$.$ Assuming the values represent signed binary

$($Indicate whether or not overflow occurs for each.$)$

$4)$ Give a BCD representation of $4693.$

a$.$ Using an $8421$ weighted code

b$.$ Using a $5421$ weighted code
