Super gaussian function
WebHere is an example of a flat-top or super gaussian: Currently the flatter the gaussian becomes, more and more information is lost, due to gaussian cutting down the edges. How can I improve the functions, or the curve fitting in order to be able to fit peaked and flat-top signals as well like in this picture: Edit: http://www.apsipa.org/proceedings_2012/papers/264.pdf

WebFor an optical fiber, we can approximate the emission with a super-Gaussian function: - For a single-mode fiber (PDF_type = 2), you can use the following fiber parameters: r f = 5 micron, N A = 0.08, φ c = asin (N A); and the following PDF parameters: G = 1; σ = 0.5 φ c 2 G (φ c in radians) - For a multi-mode fiber (PDF_type = 3), you can ... WebIf I fit a normal gaussian to a flat-top signal, the max of the gaussian will be higher than the max of the flat-top signal, that is bad. Also it will cut down the edges of the flat-top, so we …

WebThe Gaussian function is for (,) and would theoretically require an infinite window length. However, since it decays rapidly, it is often reasonable to truncate the filter window and … WebAug 9, 2024 · Inspired by the work by W. Meng et al. , we propose a Gaussian random sampling strategy for FSI. The key to the proposed sampling strategy is to perform a variable density sampling in the Fourier space and, more importantly, the density with respect to the importance of Fourier coefficients is subject to a 1-D Gaussian function.
