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.

A note that for a Fourier transform (not an fft) in terms of f, the units are [V.s] (if the signal is in volts, and time is in seconds). That's because when we integrate, the result has the units of the y axis multiplied by the units of the x axis (finding the area under a curve). Also, the integral of the square of a signal is the same in ... お茶の種類 カフェイン
