- Performance of CRC
- To detect all burst errors affecting odd number of bits
- To detect all burst errors of length than or equal to the degreeof the polynomial
- To detect with a very high probability burst errors of length greater than the degree of the polynomial
- To detect all burst errors affecting odd number of bits
