Input data into the list X and pass length of time as an arguement for the fft custom block (Or none if the time/frequency does not matter). It then does a fast Fourier transform on it. A fast Fourier transform (FFT) is like a discrete Fourier transform (DFT), but faster. Outputs will give the real component in list x2, imaginary component in list y2, frequency in units Hz in list ω, amplitude/power in list A and phase in units degrees in list φ
