Trasformazione dei dati
Trasformare i dati tra i domini del tempo e della frequenza
Funzioni
fft | Fast Fourier transform (FFT) of iddata object |
ifft | Transform iddata objects from frequency to time domain |
etfe | Estimate empirical transfer functions and periodograms |
spa | Estimate frequency response with fixed frequency resolution using spectral analysis |
spafdr | Estimate frequency response and spectrum using spectral analysis with frequency-dependent resolution |
Esempi e istruzioni
- Transform Time-Domain Data in the App
