DE TOU 3. (2.5pt) Recall in lecture 1, we discussed the concept of parity. Parity is commonly used for error detection, where an extra parity bit is generated for say 4bits of transmission. Assuming even parity, and there is no error, among every 5bits of transmission (4+1), the number of 15 is always an even number. Usually, the process of generating and checking parity between the sender and receiver is done using dedicated hardware, so in this case we are designing the checker. A. Draw the truth table of a 2bit even parity checker. A 2bit parity checker takes two inputs X₁X and produces 1bit of output D, such that when there are even number of 1s in the input, D = 0. Otherwise D = 1. You do NOT need to draw the circuit diagram for 3A. (1pt) B. Use the 2bit even parity checker as functional block, draw the circuit diagram of a 5bit even parity checker. Hint: you need to use four 2bit even parity checkers (1.5pt).
