Hilbert-huang transformation
WebAug 5, 2024 · The Hilbert-Huang Transformation (Hilbert-Huang Transform/HHT), developed by Huang et al. (1998), is a time-frequency analysis method that includes Empirical Mode Decomposition (EMD) and the Hilbert Spectrum to analyze signals. HHT is a reliable method that can be applied to non-linear and non-stationary signals which are … WebThe Hilbert-Huang transform is the combination of empirical mode decomposition (EMD) and Hilbert transform. First, EMD is an algorithm that gives you the intrinsic mode functions (IMFs). The Hilbert transform is then applied to each of the IMFs.
