## Gibbs Phenomenon In Engineering Systems

· PDF 檔案Gibbs phenomenon arises naturally in the study of Fourier series. A square wave function is shown in equation (1). It is a simple example that has been used historically in books of applied mathematics to illustrate Gibbs phenomenon analytically [2, 3, 7, 22]. x

Gibbs phenomenon

· PDF 檔案The Gibbs phenomenon was first noticed and analyzed by the obscure Henry Wilbraham. He published a paper on it in 1848 that went unnoticed by the mathematical world.

Gibbs Phenomenon

GIBBS PHENOMENON Consider the ideal LPF frequency response as shown in Fig 1 with a normalizing angular cut off frequency Ωc. 1. In Fourier series method, limits of summation index is -∞ to ∞. But filter must have finite terms. Hence limit of summation index

The Gibbs phenomenon is named for Josiah Willard Gibbs, who explained it in the April 27, 1899, edition of the journal Nature. His letter to the editor was the result of a discussion in the scientific community of the “convergence of the partial sums of certain Fourier series in the neighborhood of [a signal] discontinuity.”

## Fourier-Bessel series and Gibbs phenomena

· The Gibbs phenomena is well known for Fourier series. It’s not as well known that the same phenomenon occurs for other orthogonal series, such as Fourier-Bessel series. I’ll give an example of Gibbs phenomenon for Fourier-Bessel series taken from [2] and
