| Question 338 |
If the data frame is 1101011011 and the divisor is 10011 in a CRC error detection process, a burst error 0000010011 occurs in transmission. Justify whether it will be detected:
| With a high probability, it will be detected. | |
| It will not be detected, as the burst error is exactly identical to the divisor. | |
| With a very small probability, it will be detected. | |
| It depends on the data rate in the channel. So it may or may not be detected.

Question 338 Explanation:
CRC can detect all burst error of length less than the degree of the polynomial. But in the given question the burst error is exactly identical to the divisor, i.e., 4, so cant be detected.
Correct Answer: B
