Let G(x) be the generator polynomial used for CRC checking. What is the condition that should be satisfied by G(x) to detect odd number of bits in error?
Correct Answer: C
Question 83 Explanation:
Odd number of bit errors can be detected if G(x) contains (x+1) as a factor.
G(x) contains more than two terms
G(x) does not divide 1+xk, for any k not exceeding the frame length
1+x is a factor of G(x)
G(x) has an odd number of terms
