For question 1, if the text wording changed but the number of characters stayed the same, would this change anything? Instead of "Go UM!" if it said "Go VT!" would that make any difference in the outcome?

1. Consider a data communications system that represents characters using ASCII with odd parity. Each 7-bit ASCII character is followed by a parity bit. Specify the resulting 8-bit code word for each of the characters in the following message that is to be transmitted: Go UM! (There are 6 characters in this message, including a SPACE character and an exclamation mark.)

2. Consider the table below. Assume that the parity bit is a function of Boolean variables x, y, and z. Represent this function in the following ways:
a) as a Boolean algebra expression; and
b) as a combinational logic diagram (logic circuit).

Hope this helps you in your studies.

Yes, the outcome will change because the ASCII codes and the corresponding parity bits of the new letters V and T are different from that of U and M.
