Thanks for the clear explanation. Before I made the previous post, I was going through a draft of a post containing the gist of what you said (digital = a stream of either 1s or 0s). I couldn't get the wording right, so I gave up. (Yes, I DO censor myself sometimes. )

During the research for my lost post, I came across a website for a cable company that described their digital cables as being very faithful to the "leading edge of the digital waveform" -- which results in fewer errors seen at the receiving end of the stream. All I could think to say about that was "< cough > bullsh**!"

I guess I'd better replace all the copper cables on the inside of my computer with silver-coated, time-aligned, anti-jitter cables. Lord knows how much data is being lost to the ether with my cheap OEM cables!
