Detailed Description

crc16 is written in the last 2 bits of input vector

input: char vector of length length (packed bytes)

output: char vector of length length (packed bytes) with crc at last 2 bytes (overwrites last 2 bytes)

uses the crc16 function to calculate a 2 byte crc word and write it to the FIB (overwrites last 2 bytes)

Parameters

length	Length of input and output vector in bytes. (default is 32 for DAB FIBs)
generator	Generator polynom for shift register. (default is 0x1021 for DAB)
initial_state	Initial state of shift register. (default is 0xffff for DAB)
