Okay, David, I'll bite (I am among the 99%, I guess). Are you referring
to the highest frequency component of a modulated carrier or the
information bandwidth of a modulated signal? If the former, I agree (e.g.
undersampling of modulated RF carriers is done all the time). If the
latter, then please explain :)
