11. Give an example of an 8 bit 2's compliment subtraction that results in overflow. Work out the subtraction in 8 bit 2's compliment and then convert each value to decimal to prove that overflow occurred. Provide a brief explanation of your example including why overflow occurred. 12. Is a "discarded carry" the same as overflow? Provide examples to support your answer. 13. How many different (i.e.: unique) representations can we produce with: a. four bits b. seven bits 14. Convert the following real numbers to binary values using fixed point notation (keep 8 binary places total 3 to the left of the radix point and 5 after the radix point). a. 7.50 b. 3.25 c. 2.10 15. Convert the following unsigned fixed point binary representations to base 10 (you can assume these are positive values): a. 10110.11011 b. 10011.100101 16. Represent-13.65625 base 10 in binary using the sign, mantissa, and exponent formula (sign * mantissa * 2^exponet). Show your work for this question to receive full marks.
