PyHHT Tutorials — pyhht 0.0.1 documentation - Read the Docs
PyHHT is a Python module based on NumPy and SciPy which implements the HHT. These tutorials introduce HHT, the common vocabulary associated with it and the usage of the PyHHT module itself to analyze time series data.

We implement the Hilbert-Huang transform in python. The main HHT algorithm is implement in torchHHT/hht.py . torchHHT/visualization.py provides functions to plot the extracted IMFs and the resulting Hilbert spectrum.
The Hilbert-Huang Transform — emd 0.0.1.dev239 documentation
The simplest HHT is computed by emd.spectra.hilberthuang_1d. This returns a vector containing the weighted histograms for each IMF within the bins specified by edges. Here, we defined a set of linear bins between 0 and 100Hz and compute both a weighted and unweighed HHT.

Compute the mean of the envelopes and the mode amplitudes. Check if there are enough extrema (3) to continue sifting. Evaluate the stopping criteria for the current mode. Empirical mode decomposition. The timestamps of the signal. Threshold for the stopping criterion, corresponding to θ1 θ 1 in [3]. Defaults to 0.05.
HHT方法的python代码完美实现——结构时变模态参数识别方法_python实现hht …
文章介绍了黄鳄提出的基于经验的HHT方法，用于处理非线性、非平稳数据。HHT包括EMD和Hilbert变换两个步骤，通过示例展示了如何生成信号、进行HHT分析、选择IMF并验证其能合成原始信号。提供的Python代码实现了这一过程，适用于工程信号分析。
