Andy,
hm, should we at least be warning about HPFs that cut off below f_s/2?
John,
I might argue that in this specific application, the idea of "hey,
let's just subtract what we don't want" wouldn't be the worst idea;
Simply something like
input --+-->LPF---+---> Sig1

I'm setting up a measurement program to look at the channel power inside
and outside a defined bandwidth centered at zero. The idea is to get
the ratio of the power within a low pass filter (nominally 500 Hz), and
the power in the rest of the spectrum (192 kHz) with that same 500 Hz
