You are implementing a CRC polynomial check code using the generator polynomial x⁴ + x² + x + 1. Suppose the following message is to be sent: 10110011. (a) What is actually transmitted? (b) If the message is received without error, show how you would have verified this. (c) Suppose the first and last bits of your transmitted message were changed by errors on the line. Would you detect the error? Show your work. (d) Is the generator polynomial above better or worse than the generator polynomial x⁴ + x³ + 1? Explain your answer.
