How to do a discrete Fourier transform (FFT) and to plot the amplitude and phase spectrum in MATLAB
In this short video, I explain how to load a time function (some simulated signal) and the corresponding (equally spaced) time steps from a text file into MATLAB. After plotting the time function, the discrete Fourier transform is used to convert the signal from time domain into frequency domain an to calculate the spectral components of the ...
