Assignment:
Question 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.)
Question 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).
X Y Z Parity Bit
