Morris Mano Edition 3 Exercise 7 Question 42 (Page No. 306)
It is necessary to formulate the hamming code for four data bits $D _3, D _5, D _6 and D _7$ together with three parity bits $P _1, P _2 and P _3$. evaluate the 7bit composite code word for the data word 0010. Evaluate ... error detection in the code. Assume that error occurs in the bit $D _5 and P _2$. Show how the error is detected.

Andrew S. Tanenbaum Edition 5th Exercise 3 Question 12 (Page No. 252)
Suppose that data are transmitted in blocks of sizes 1000 bits. What is the maximum error rate under which error detection and retransmission mechanism (1 parity bit per block) is better than using Hamming code? Assume that bit errors are independent of one another and no bit error occurs during retransmission.
