Y(t) =∑i ai yi(t, k) y (t) = ∑ i a i y i (t, k) this equation would as good as possible mimic (inverse fourier) your sequence. if you do so you will understand that the transform is exactly the opposit way, and what its details value for you. i did this quite often and works great to have sequences comprehensive. If you read onwards in the documentation on fftshift: "it is useful for visualizing a fourier transform with the zero frequency component in the middle of the spectrum." the shift is not necessary to perform the fft, but it is handy to visualise the fourier transform. A frequency bin in 1d generally denotes a segment [fl,fh] [f l, f h] of the frequency axis, containing some information. it is defined between a low and a high frequency bound fl f l and fh f h. it is related to the series of ranges of numerical value used to sort data in statistical analysis.

The fourier transform is a mathematical technique used to convert signals from time or space domain to frequency domain. in context, the fft () function in scipy computes the discrete fourier transform (dft). the result of a dft on real world data can be challenging to interpret, mainly because the output frequencies are arranged in a mix of.
