Convert the decimal number $143$ to

a$.$ unsigned binary using $8$ bits

b$.$ hexadecimal

c$.$ represent $-143$ using a $16-$bit signed binary number

Show the decimal equivalent of the two $8$ bit binary numbers below if they are

interpreted as both unsigned and signed:

Perform the operation on the two pairs of numbers below; each number is $4$

bits. Show the operand and the results in decimal for both unsigned and

signed binary. $($Indicate if there is or is not overflow for all $4$ answers$)$

Convert the two hexadecimal numbers

a$.0FE6C$

from hex to binary

b$.0x0BA7$

from hex to decimal $($assume unsigned$)$

Give a BCD representation of the decimal number $7348.$

a$.$ Using an $8421$ weighted code

b$.$ Using a $5421$ weighted code

c$.$ Using an ASCII character table
