WebAfter all we increase the number of available patterns by 2nx by adding the checksum and there are only n single-bit errors per pattern and n(n-1)/2 double bit errors. If n + n(n-1)/2 = n(n+1)/2 < 2n then we can potentially detect all double-bit errors The procedure for generating a CRC relies on a predetermined word of m-bits called WebWhat is checksum and what kind of errors, undetectable by checksum? When we are transferring data (usually in packets) due to the disturbance in the network, some of the bits get corrupt and the bits are changed. Most of the time bits are shuffled and the placement or order of bits is changed. So these kinds of errors are undetectable by checksum.
