WebThe Gibbs phenomenon is a specific behavior of some functions manifested as over- and undershoots around a jump discontinuity (Nikolsky, 1977b, § 15.9; Hewitt and Hewitt, 1980; Jerri, 1998). The Gibbs phenomenon is typical for the Fourier series, orthogonal polynomials, splines, wavelets, and some other approximation functions. WebAbstract. Recently, T. H. Fay and P. H.
