EMD: Empirical Mode Decomposition¶
Python tools for the extraction and analysis of non-linear and non-stationary oscillatory signals.
Features¶
Sift algorithms including the ensemble sift, complete ensemble sift and mask sift
Instantaneous phase, frequency and amplitude computation
Cycle detection and analysis
Hilbert-Huang spectrum estimation (1d frequency spectrum or 2d time-frequency spectrum)
Second layer sift to quantify structure in amplitude modulations
Holospectrum estimation (3d instantaneous frequency x amplitude modulation frequency x time spectrum)
