Reconsider 111 011 000 in a binary format 2.1) Find the codeword corresponding to this dataword using the CRC error detection technique, and the divisor polynomial g(x) = x°+x?+1. Do Binary division with Os and 1s. 2.2) Compute now the codeword corresponding to this dataword assuming that the divisor polynomial that is used is f(x) = x+1. Do Polynomial division. 2.3) Assume that an error corrupted the first two bits of the dataword; show how the CRC technique allows you to detect such an error using the divisor of question 2.2.
