WebJan 23, 2015 · A Fourier series means the amplitude of the different harmonics, who are an integer multiple of a base frequency. It is easy to see, that this base frequency simply doesn't exist in your case. Although a Fourier transform of a such function of course exist, which is trivially F(s) = δ(t − ω1) + δ(t − ω2) Share Cite Follow Web2 Answers. Sorted by: 1. The fourier series is infinite, you can only graph a partial sum of the series for your interval. My guess is that it will look something like this in the first 3 terms: See how the graph is starting to …

WebThe Complex Graph Fourier Transform (CGFT) Any Hermitian matrix can be diagonalized by a unitary matrix, then (5) where are the eigenvalues of ( a diagonal matrix, ) and (columns of ) are the corresponding orthonormal eigenvectors, so is unitary. The eigenvalues are real due to the Hermitian property. WebJun 26, 2024 · The fft is at heart an operation using complex variables. You can use sines and cosines, multiply amplitudes by 2, except don't multiply X (1) by 2, all that kind of stuff. Some of that is good for plotting purposes. But if you want to get back to the time domain it's far easier to use complex amplitudes and exp ( i* ...).
