[Discuss-gnuradio] atsc signal plots

[Charles Swiger]

Here's some pictures for Friday - I though these were interesting,
the output of the 0.9 atsc equalizer showing the 8 levels getting
more distinct with every field:

Zooming in:

shows the field sync which is largely made up of only +5/-5,
and zooming in on the beginning:

you can make out the +5 -5 -5 +5   segment sync, followed
by the start of the pn511 pattern (7 -5's, +5, -5, then 
8 +5's).



The 2.0 port isn't doing as well - a few eyes show up here
and there:

and that's with the NOP equalizer. The LMS eq is all noise
all the time.
