Hi,
Is it possible to plot/export the output of the FFT glyph in complex for?
I am interested in obtaining the frequency spectrum amplitude of a timehistory with magnitude/phase format.
Thanks
Manuel

Manuel Hi Manuel, In GlyphWorks, you can obtain complex frequency data from the Waterfall analysis and Joint Time frequency analysis glyphs. Regards. Benm.

Hi Manuel, The frequency spectrum glyph is rather dedicated to random stationnary signals and therefore only gives you informations related to the Amplitude of the FFT. If you're looking for Amplitude + Phase, i'd recommend using the FrequencyResponseAnalysis glyph: the excitation is your signal, the response is the same signal. You'll get the Gain and Phase of your signal (just Turn CreatePhaseData to True). Hope this helps, Fred
