//How many points can be plotted in a frequency range (Delta F) where Delta F is -3 dB frequency band around a peak ?//
As many as the user desires, limited only by computation time. We've done a lot of testing with 10 and 100 points per FFT bin (1/T).
//Does this number depend on the peak...
//It could be very useful in experimental modal analysis.
Does the method work with short-duration time signal ?//
The method will always work as well or (usually) better than FFT with no requirement to be a power of 2 number of points and no penalty for any number of points. It is the most...
//Your EI appears to offer frequency resolution better than 1/T. Is this the case?
Sorry now I've actually read the discussion, not just looked at the graphs. It seems to me that this method suffers from the well known pitfalls of zero padding. That is, you are assuming that there is only one...
A colleague and I are looking for feedback on a technique we've implemented and code we've written to use Fourier transforms to determine frequency, phase, and amplitude of oscillatory components more accurately. This program has the same functionality as an FFT (Fast Fourier transform), but...
