A 12-bit Hamming code word containing 8 bits of data and 4 parity bits is read from memory. What was the original 8-bit data word that was written into memory if the 12-bit word read out is as follows: 101110000110
Show how you got your answer. 5.12 For the 8-bit word 00100001, the check bits stored with it would be 1001. Suppose when the word is read from memory, the check bits are calculated to be 0101. What is the data word that was read from memory? You manu check hits are needed if the Hamming error correction code is used to 12

Hamming & SECDED Code (a) For data, using 3 Hamming code parity bits determine the maximum number of data bits that can be protected. (b) A SECDED encoded character has been retrieved, with the hexadecimal value of 409(base16). You may assume that the SECDED parity is even. 1. Was there an error in transmission? Explain your answer. 2. If there was an error, either correct it (reporting the corrected ASCII character) or explain why it could not be corrected (Show...
23. The followings are 12-bit words read from the memory. Suppose when the words were sent to the memory, the check bits are calculated to be 10001. Using Hamming error correction code, find the new check bit, the syndrome word and the original word stored in the memory for the word retrieved given below. a. 1000 1101 0010 (12 marks) b. 1101 1000 1101 (12 marks)
Practice 5 The followings are 8-bit words is stored in the memory. Suppose when the words were read from the memory, the check bits are calculated to be 0010. Using Hamming error correction code, find the he check bits stored together with the word, the syndrome word and the word fetched from the memory for the word given below. a) 1111 0001 (11 marks)
Q3. In a (7,4) Hamming Code, three parity bits p1, p2, p3 are added to four data bits dl, d2, d3, and d4, and the coverage of each parity bit is as shown in the table below: Bit position 2 3 4 5 6 7 Encoded data bits p1 p2 di p3 d2 d3 d4 da X p1 X X X x Parity bit coverage p2 х X X p3 X X X х 1) (3 pts) Assume even parity...
In Hamming codes with 8 data bits and 4 parity bits: If d3 is the only error in transmission, what does the receiver do? If d3 and d6 are the only two error bits in transmission, what does the receiver do? If the receiver ends up correcting d6, what are three possible scenarios that could have happened (there are many more scenarios, but you need to list only three)?
Given a 8-bit word 00111001, suppose when the word is read from memory, the new check bits are calculated based on the fetched reading is 0001. Provide details regarding how you get the answer. Part 1) Is the data fetched correctly? Part 2) If no, is the data bit or check bit goes wrong? Part 3) What is the additional checking bit that you need to store in the memory if you want to use it to detect two bits...
y7 Assume a 12 bit Hamming code as we discussed in class is used to transmit one byte of data. List the pit positions that parity bits p1, p2. p3 and p4 are formed. Suppose that even parity check is used. What are the bits transmitted for the following ASCII codes?
