WebApr 15, 2024 · Background Anesthesiologists are required to maintain an optimal depth of anesthesia during general anesthesia, and several electroencephalogram (EEG) processing methods have been developed and approved for clinical use to evaluate anesthesia depth. Recently, the Hilbert–Huang transform (HHT) was introduced to analyze nonlinear and … WebDec 7, 2024 · Huang et al. [6] developed a method for nonlinear and nonstationary signals, which is called the Hilbert–Huang transform (HHT). This method consists of two parts: the empirical mode decomposition (EMD) and the Hilbert spectral analysis (HSA).
