3. Using Hamming algorithm a. How many parity bits are necessary to encode a word of length 12? b. Find the code word for representing the 12-bit information word - 1001000110104 c. Assume that at the receiving end, the bit at position 10 of the code word has changed. Show how the error is detected and corrected. 3. Using Hamming algorithm a.
