Fit fft
WebI would like to fit it in the form: y = A sin ( B x + C) + D where A, B, C and D are constants. The only constants I really care about is A and B so that I can get the amplitude and time period.. Edit: I think I should clarify.. The data that I will be fitting will likely be noisy, so I was thinking that sine fit might give me a more accurate ... WebFeb 11, 2024 · Suppose I have some data, y, to which I would like to fit a Fourier series. On this post, a solution was posted by Mermoz using the complex format of the series and "calculating the coefficient with a …

WebApr 7, 2024 · Hi, I am trying to recreate this figure but I can't manage to figure out how to fit a smoothed line to summarise the frequencies. Also, the reference figure also includes the SEM which I'm struggling to recreate. My current plot is the grand averaged frequency spectra of simulated EEG data from 98 participants. Thanks!
