1 Say which of the following 2 's complement numbers on 8 bits, represented in compact form in hexadecimal base, is the closer to zero. AA,F3,7F 5 Represent the number 8 in two's complement in base two on four bits. Illustrate the various steps and any problems. Then convert it to base 16 (always in two's complement). 3 Add the two 8-bit numbers in two's complement (base 16) A3 and 7F. Illustrate the various steps and any problems. 4 Having 6 bits available, indicate, both in binary and in decimal, the largest and smallest admissible value for representation in CA2 and pure binary. 5 The following hexadecimal numbers represent binary numbers encoded in CA2 over 8 bits. Record these numbers in order ascending of value. (It is not necessary to write the corresponding decimal value). 01A2B232807FFF
