Assume we need to create codewords that can automatically correct a one-bit error. What should the number of redundant bits (r) be, given the number of bits in the dataword (k)? Remember that the codeword needs to be n = k + r bits, called C(n, k). After finding the relationship, find the number of bits in r if k is 1, 2, 5, 50, or 1000.
