Re: Hello??
said by Fluker  :have you ever actually seen an hdtv signal OTA? It just plays like a scratched dvd, or satelite during a light storm. You'll see artifacts and some jumping, but it's not quite on or off like a light switch. analog is such a waste of potential bandwidth. A signal that had some snow is FLAWLESS in digital. Hmmm...My neighbor is a broadcast engineer and his testing makes him an advocate of Digital OTA vice digital over AT&T cable. But time will tell when we all have to shift.
And yes, digital is more efficient, but conversely is less fringe area friendly.

Analog extends much further to the right past digital and the digital is a much sharper cutoff. Digital seems to be an all or nothing proposition and unlike FM and AM, if you miss any data you lose all of it.
We played around with the digital radios a year or two ago and found that they stay much clearer and seem to have more information carrying capability for a given bandwidth, however if you are working under marginal conditions, they stopped working where a FM radio could still make contact (granted we sometimes had to repeat several times it was so poor, but it at least worked).

It is more like this with the top line representing digital vs analog on the bottom, which extends further right |
