From a practical "engineering" POV, they can't necessarily do
it in the same time. A digital bandpass filter is not a big deal,
but a 1GHz one is probably impossible with any existing
computer, and probably cost-prohibitive much above 100MHz.

If it can't run fast enough, it's useless in practical terms,
the signal won't wait. ;-)
