Suppose we want to transmit the message 11011101 and protect it from errors using the CRC polynomial x4 + x3 + 1. -------------- Use polynomial long division to determine the message that should be transmitted. --- Show the CRC computation done at the receiver in case of no errors. --- Suppose the leftmost bit of the message is inverted due to noise on the transmission link. What is the result of the receivers CRC calculation? How does the receiver know that an error has occurred?
