Sigh! Yes of course digital propagates as an analog signal. The key is to understand that the threshold between a 1 or a Zero is so large and that checksum and other additional packet error checking information allows a packet of digital data to arrive in the memory of downstream devices perfectly.
If digital was not such an incredibly robust method of data storage and transmission then internet and computers and software would not function at all. What errors we do encounter are down to hardware or programming errors in the devices and switches themselves and not the ethernet wires which work to spec or don't work (in which case a dropout can occur)
