Unknown Artefacts – Purring

I’ve become involved in attempts to solve the mystery of the Unknown Artefact. I’ll write more about this later, but currently I have no “in character” story for that involvement, so I’ll just post some minor information for today.

I’ve been concentrating on building up a list of transcripts of the purrs in the audio signal. So far, I collected 18 sequences, of 111 different “bytes”. There are 36 unique bytes.

  • No byte so far has a triple or longer sequence of consecutive bits
  • The distribution is clearly not even. See the following graphs:
