Web13 nov. 2024 · CRC-16 CRC-32 CRC-64 CRC-1 (parity bit) is a special case Generally, we can refer to a CRC as CRC- n, where n is the number of CRC bits and the number of bits of the polynomial’s binary representation with a dropped first bit. Obviously, different CRCs are possible for the same n as multiple polynomials exist for the same degree. children\u0027s social care somerset
