Consider a CRC code with a generator polynomial of g(x) = x4 + x3 + 1. Suppose the codeword length is 8. Answer the following questions, with proper justifications. i. (10 points) Give an example of undetectable error burst of length 6; ii. (10 points) Give an example of undetectable 6-bit error; Consider a CRC code with a generator polynomial of g(x) = x4 + x3 + 1. Suppose the codeword length is 8.
