Question: 9. Consider the polynomial G(x) = x 4 + x 3 + x 2 + 1. A CRC code uses G(x) as the generator polynomial.

9. Consider the polynomial G(x) = x4 + x3 + x2 + 1. A CRC code uses G(x) as the generator polynomial.

(a) The number of data bits is 5. How many bits in total (data plus CRC) are there in a codeword?

(b) The following word (including CRC) is received: (111101100). Is there any error detected?

(c) Draw the shift-register diagram for G(x).
