7. 8. (3 points) From the results of the previous two questions, generalize the range of values in decimal) that can be represented in any given x number of bits using: a) Signed magnitude b) One's complement c) Two's complement (3 points) Using arithmetic shifting, perform the following assume the binary strings are in 2's complement format and Use 8 bits for binary numbers): a) double the value 000101014 b) quadruple the value 01110111 c) divide the value 11001010 in half- 9. (5 points) Decode the following ASCII message, assuming 7-bit ASCII characters and no parity: 1001010 1001111 1001000 1001110 0100000 1000100 1001111 1000101 10. (3 points) Suppose we are given the following subset of code words, created for a 7-bit memory word with one parity bit: 11100110, 00001000, 10101011, and 11111110. Does this code use even or odd parity? Explain
