The generator polynomial, P(x) = x* + x +1 (i.e., P = поо). 1) Encode the data bit sequence M(x) = x° + +1 (i.e., M= 000011001) using the generator polynomial and state the codeword. 2) Show that the error detection scheme at the receiver can detect the received codeword and contain no error.

A block of bits with n rows and k columns uses horizontal and vertical parity bits for error detection. Suppose that exactly 4 bits are inverted due to transmission errors. Drive a mathematical expression of n and k for the total number of different cases where these 4 error bits will be undetected. Show each important step of your derivation. (Hint: the error bits will be undetected if all the parity bits computed from the block remain unchanged.)
