Computer architecture and organization
Consider the last 4 digits of your student register and append with 1122 and represent the number in binary number for data sequence. a) Apply hamming method to find the parity/check/skip bits and show the whole data sequence transmitted. b) Flip the 5th bit from ... 3 8 1 1 2 2 Binary Sequence 0 0 1 0 1 1 0 0 The data sequence for the example is: 00101100

Digital Logic | Doubt
Hamming Distance: We can calculate how much Hamming Distance should be there so that we can correct any wrong bit Hamming Code: By Hamming Code we can correct any wrong bit. Questions: 1] Are they both different techniques or there is relation ... Hamming Distance in any two numbers). 2] Why should anybody use Hamming Code where we can correct error by Hamming Distance?

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 7-bit 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.
