Digital transmission refers to the whole transceiver system, not just the transmission medium. If I can put a "1" in and reliably get a "1" out, it doesn't matter that it was only a 0.9 part way down the wire.

- lmilcin 8y agoI suppose you need to read up on digital protocols, it is all well handled. If it wasn't there could be no Internet or digital media or even processors or motherboards.
- TylerE 8y agoThat is a higher level, though. I'm just so tired of all the bullshit where it "Must be a 1 or a 0". That is patently not true. HDMI video, to name one example very relevant to this thread, has no error correction, and bit errors will indeed crop up as the "sparkling" artifacts GGGGGP reported.
