4. A linear code is given by the encoding function y = ax+b (mod 26) and the decoding function x = cy + d (mod 26). (a) If a 11 and b = 2, what are c and d, where c and d are integers from 0 to 25? = (b) If we are sure that E encodes to H while B encodes to M, determine a, b, c, d where they are each integers from 0 to 25. (Recall A=0, B=1, ...)
