student ID: 702 change to binary format

Reconsider your student ID in a binary format (as explained in the previous question) as the dataword. 2.1) Find the codeword corresponding to this dataword using the CRC error detection technique, and the divisor polynomial g(x) = x +x++1. 2.2) Compute now the codeword corresponding to this dataword assuming that the divisor polynomial that is used is f(x) = x +1. 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
