1.	What is the total block length ‘n’ of a Hamming code?(a) 2^r(b) 2^r-1(c) 2^r-1-1(d) 2^r+1
Answer» Correct option is (b) 2^r-1 The best I can explain: Hamming codes are a class of binary linear codes, hence r>=2. For a hamming(7, 4) code, the block length ‘n’ is 2^r-1 where r is the parity bit. Here, r=3.
