Question 6: The parity bit check protocol is a logic circuit generated by the sender of digital data and checked by the receiver, allowing the receiver to verify whether the data was transmitted correctly or incorrectly. There are two types: even parity bit and odd parity bit. The even parity bit generator logic circuit produces a logical "1" if the number of logical "1"s in the transmitted data is odd, and a logical " 0 " if the number is even. On the receiver side, there is a parity bit error-checking logic circuit that examines both the data and the parity bit to determine whether the data was transmitted incorrectly or correctly. Based on this: a) Write the truth table for the even parity bit generator logic function for 3-bit data. b) Write the truth table for the even parity bit error-checking logic function on the receiver side, which handles a total of 4 bits (including the parity bit).
