The CRC is calculated using the following generator polynomial: x8+x2+x+1
a- Find the CRC bits for the following information bits 1111 0000 0000 0000
b- Can this code detect single errors, double errors, and triple errors? Explain why.
c. Draw the shift register division circuit for this generator polynomial.
Homework Answers
A-- 
B ---yes this code can detect single errors,double errors and triple errors. In general, all CRC polynomials can detect a single bit error regardless of message length. All CRC polynomials have a "cylic" period.
C----- i need more information.
