None of the Q&As I've seen thus far have given a clear answer to what seems like a simple question: assuming I know the
SampleRate, and one or both of
DesiredFrequencyResolution, how do I determine the
WindowSize and Number of Points for an STFT(
nfft)? Working with complex/baseband signals if that makes a difference.
- This answer seems to be saying that frequency resolution/resolution bandwidth is just
- However that doesn't give me a formula for relating desired time resolution to STFT input arguments. Nor does it give me a formula for determining
WindowSize(I've seen several explanatinos which say
WindowSizeshould equal the
NumberFFTPoints) but would like to double check that this is correct and/or understand what happens when they are different.
