Suppose we want to transmit the message 10011010 and protect it from errors using the CRC polynomial x^2+1. Encode the data bit sequence using the generator polynomial and give the code word. Using this polynomial, can all single-bit errors be detected? If not, give an example scenario of errors that goes undetected.
