Consider a CRC code with a generator polynomial of g(x) = x 4 + x 3 + 1.
Suppose the codeword length is 8. Answer the following questions, with proper justifications. i. (10 points) Give an example error vector of undetectable error burst of length 6 (L = 6). ii. (10 points) Give an example error vector of undetectable 6-bit error (M = 6). iii. (10 points) Give an example error vector of undetectable error that is both a 5-bit error and an error burst of length 8 (M = 5 and L = 8).
