WebDec 20, 2010 · Abstract: The Hilbert-Huang transform (HHT) is a new method of analyzing non-stationary and non-linear time series data. Based on realization of HHT method in MATLAB software, we find that analytical capacity of HHT to time series in time-frequency domains stands out. WebNov 26, 2024 · 2.2 Hilbert–Huang Transform. 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.
