Single parity code The codewords of a parity code are obtained by adding a parity bit, Le.

such that the number of bits '1' in the codeword is even. Consider the case wherem=4.

1. Find the codeword of the useful word (l 0 1 1), and determine all detectable errors.

2. Give an example of a non-detectable error.

3. Calculate the following characteristics of this code: capacity, density, coverage rate, and redundancy rate.
