Question

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)
