This is sort of a math question, sort of a signal processing engineering question.(adsbygoogle = window.adsbygoogle || []).push({});

I've found 3D graphs of real vs imaginary vs time/frequency to be very helpful in my understanding of Fourier transforms, complex signals, and the like. Is there a convenient/clever name for these graphs? I don't see them used very often, which I think is a bad thing.

Examples: http://www.complextoreal.com/tfft2_files/image016.gif" [Broken]

For instance, http://www.vnij.com/company/press/image_library/full_res/spectrogram.gif" [Broken] isn't called "graph of frequency and phase vs amplitude on logarithmic axes"; it's called a "Bode plot".

Just wondering.
