WebA fast Fourier transform (FFT) is a highly optimized implementation of the discrete Fourier transform (DFT), which convert discrete signals from the time domain to the frequency domain. FFT computations provide … WebSep 9, 2014 · The important thing about fft is that it can only be applied to data in which the timestamp is uniform (i.e. uniform sampling in time, like what you have shown above).In case of non-uniform sampling, please use a function for fitting the data.
