That only works if your reference clock is stable enough over the collecting
period.
I'm far from a DSP wizard. Assume I have a signal at 100 kHz with a
bandwidth of 1 kHz. (or pick any numbers you like) How many samples per
second do I need? How stable does my sampling clock need to be if I collect
data for for N seconds?
Is "stable" the right term? What's the right way to think about the question
I'm trying to ask?
