Webx = hilbert (xr) returns the analytic signal, x, from a real data sequence, xr. If xr is a matrix, then hilbert finds the analytic signal corresponding to each column. example. x = hilbert (xr,n) uses an n -point fast Fourier transform (FFT) to compute the Hilbert transform. The input data is zero-padded or truncated to length n, as appropriate. WebAug 5, 2024 · Hilbert–Huang Transform can be used to overcome the non-stationary and non-linearity problems of a signal for time-frequency analysis. Huang et al. (1998) shows that the Hilbert Spectrum obtained from HHT is more meaningful than the Fourier Spectrum when analyzing the frequency spectrum of a non-stationary signal.
