I have a completely different view of these test results.
In both cases, the outcome should have been obvious.
It should have been obvious that 8-VSB *could be made* to work just
fine, and it is just as obvious that using white spaces will definitely
be problematic. You don't need clueless politicians getting yanked
around by self-serving marketers to decide on such straightforward
technical facts.
What's wrong with simple truth? That's what I don't understand. Why
isn't it clear when self-serving parties are voicing their self-serving
agendas?
