[BC] Frequencies of DTV signals...

[Burt I. Weiner]

The assigned channel will be the channel limits.  For example: 
192-198 for channel 10.  Now that Analog is gone there is no longer a 
need for precision offsets from a first adjacent lower NTSC 
signal.  Most stations will place their pilot signal 0.309441, Hz +/- 
1000 Hz, up from the lower edge of the channel.  So, for channel 10 
the pilot would be 192,309,441 Hz.  The pilot can be seen as a spike 
on the lower edge of the "box" when looking at a DTV signal with a 
spectrum analyzer.
