comp.dsp | Gibbs phenomenon and spectral leakage.
May 6, 2009 · Gibbs phenomenon has to do with the FT representing a discontinuity by a continuous function. The Fourier basis vectors can represent continuous signals, but only approximate discontinuous signals. Spectral leakage has to do with how the vectors that represent signals are being mapped onto the Fourier basis vectors.

May 10, 2007 · The Gibbs phenomenon is a direct result of your signal being bandlimited; you need infinite bandwidth to have completely "sharp" edges, and obviously you can't do that with a sampled signal. Windowing can't really help you; when you interpolate, you don't get any new information about the signal.

The side-lobe height is instead a result of the abruptness of the window's transition from 1 to 0 in the time domain. This is the same thing as the so-called Gibbs phenomenon seen in truncated Fourier series expansions of periodic waveforms.

May 6, 2009 · Gibbs was only 9 years old at this time! If is unfortunate that when Maxime Bocher put a thorough mathematical analysis to the fourier problem in 1906 he attached the name "Gibbs phenominon" to the problem. Although these days we at least recognize the associated Wilbraham constant. FWIW, Clay Reply Start a New Thread
