Dear All,
I intend to sample and store some waveforms. I get the FFT of the waveform and it looks like the attached graph. My problem is that I can not determine the Nyquist frequency on a graph like this, since its a wide band signal.
Kindly please bear in mind that I have to find a balance between accuracy and storage cost. I would like to know how people normally sample such signals and how much accuracy cost is normally affordable. Any clue to follow up or any guidance backed up by theory or a cite-able practice would be most appreciated.
Thanks
Arash
