That is right. Analog signals get snowy if the signal level is weak. The
digital signal strength does not mater as to quality of the picture. You
either have enough signal for the receiver to work or you get a blank
screen. Under some fading conditions you may see the picture look like
square blocks and frozen up. That is where the signal totally goes away.
It does not mater if you have 100% 0r 10 % signal, if it is enough for the
circuits to get the information, the quality will be the same.

IIRC, 70% is enough signal you should get a perfect picture (as good as
100% signal).

10% is low and since these things are inconsistent will likely go too
low at times. You'll get a blocky picture and bup-bup-bup audio
(something I've seen WAY too much).
