crc16

baseband.mark5b.header.crc16 = <baseband.base.utils.CRC object>

Cyclic Redundancy Check.

See https://en.wikipedia.org/wiki/Cyclic_redundancy_check

Once initialised, the instance can be used as a function that calculates the CRC, or one can use the check method to verify that the CRC in the lower bits of a value is correct.

Parameters:
polynomialint

Binary encoded CRC divisor. For instance, that used by Mark 5B headers is 0x18005, or x^16 + x^15 + x^2 + 1.
