How to plot FFT data in Matlab?
Y = fft(X); Compute the single-sided amplitude spectrum of the signal. f = Fs*(0:(L-1)/2)/L; P2 = abs(Y/L); P1 = P2(1:(L+1)/2); P1(2:end) = 2*P1(2:end); In the frequency domain, plot the single-sided spectrum.
What does FFT output in Matlab?
A 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 information about the frequency content, phase, and other properties of the signal.How do you select data points in Matlab?
Use normal button clicks to add points.
A shift-, right-, or double-click adds a final point and ends the selection.
Pressing Return or Enter ends the selection without adding a final point.
Pressing Backspace or Delete removes the previously selected point.Double click on the scope of the signal for which you want to perform the FFT Analysis and go to Logging Tab, tick the “Log data to the workspace” option and select Save format as “Structure with Time” and click on Apply.
Run the simulation.
Double click Powergui >> Tools >> FFT Analysis.
