WebSep 2, 2008 · Demonstration of Gibbs' Phenomenon. This short m-file demonstrates the Gibbs' phenomenon in Signal Processing. It clearly shows the "ringing" when the number of Fourier components are enhanced while synthesising a square waveform. WebThe main Theorem implies that this sequence converges to f ( x) except at the point x0 = 0, which a point of discontinuity of f ( x ). Gibbs got interested to the behavior of the sequence of Fourier partial sums around this point. …
