My apologies for not stating a reference. Was thinking in terms of

Whew! Thanks... I'm glad to see this post. I was about to post a
question about this, but you cleared it up Avery (or is it Paul...or er,
Len...)
Digital TV
has an almost infinite S:N ratio down to the lower limit of its
processing
capability, none of the noise "snow" effects seen with early days of
analog TV and distant TV stations "down in the mud."
If it is like digital cellular, it will have really good noise down to
some level _at which_ an analog signal would still be watchable (with
noise), then just DIE completely - where the analog signal would me
watchable depending upon the viewer's noise tolerance.
