Question: Suppose to transmit the data 1 1 0 0 1 0 0 1 and protect it from errors using the CRC polynomial x ^ 3

Suppose to transmit the data 11001001 and protect it from errors using the CRC
polynomial x^3+1
. Use polynomial long division to determine the codeword that
should be transmitted. Corrupt the left-most third bit of the transmitted codeword
and show that the error is detected by the receiver using the CRC technique.
