Hello,
I joined this group recently and have learnt a lot. I had a rather fundamental question. Suppose I sample the
IF output (say, centered at 40 Mhz) of a tuner/mixer tuned to a ATSC DTV channel (6Mhz wide), and I want to detect the
pilot frequency which is added to the channel during transmission, would I have to sample the IF
at much higher than 2*Nyquist fy? The reason I ask is that the pilot occurs at a fixed fy relative to the tuned
channel.
Thanks. Dinkar.
