WebJun 6, 2008 · Hilbert-Huang transform, consisting of empirical mode decomposition and Hilbert spectral analysis, is a newly developed adaptive data analysis method, which has been used extensively in geophysical research. WebTheHilbert Huang transform(HHT) is a time series analysis technique that is designed to handle nonlinear and nonstationary time series data. PyHHT is a Python module based on NumPy and SciPy which implements the HHT.
