HHT is a time–frequency–energy method for the analysis of nonlinear or non-stationary data sets, the process of which can be divided into two parts: EMD and the Hilbert transform (HT) . For extracting the basis for the HT, EMD has been proposed to generate finite component sets empirically from the original data. WebHilbert–Huang transform (HHT), by Huang et al. (1996, 1998, 1999) seems to be able to meet some of the challenges. The HHT consists of two parts: empirical mode decomposition (EMD) and Hilbert spectral analysis (HSA). This method is potentially viable for nonlinear and nonstationary data analysis, especially for time-frequency-energy ... diamond park in usa
