If any XORing, carrier signal adding, previous-bit input, or other potentially cryptographic process is involved, then it is evidently limited in size and complexity.
For example, when the stock configuration is tweaked on active pattern number, we do not see a completely new waveform but only very small differences in a very small number of locations (UNIX diff).
If there is any kind of XOR-like behavior on the plaintext bit (byte?) data, then it is less of a giant block cipher and more of a stream cipher, possibly involving a very short feedback loop.
