SOLVED: A category of error-detecting (and correcting) code, called the Hamming code, is a code in which dmin = 3. This code can detect up to two errors (or correct one single error). In this code, the values of n, k, and r are related as: n = 2r - 1 and k = n - r. Find the number of bits in the dataword and the codewords if r is 3.
