It may not be easy to do hardware wise, but just shifting the sample rate to fit ones bandwiidth (FFT size and resolution, ...) of interest seems ideal to me. This is often a problem in biological acoustics for example because one needs a wide variety of bandwidths for different species from blue whale to bat, but A/D cards are made at specific sample rates often not quite meeting the requirements of bandwidth and resolution ... no doubt similar problems exist in the electromagnetic spectrum.Is there any other way to decrease the sample rate beside the decim_rate?Why would you want to do that?
