(b) Consider the use of the Hamming code to send this 8-bit message (00111101). (i) Determine the Hamming code word for this message. (ii) Suppose data bit 6 in the above question sustains an error and is changed from 1 to 0. Determine the syndrome and hence show that the Hamming code will identify the error.
