About¶
This package is provides an easy way to do a signal decomposition and the time correlation between two signs. Is based on the methods Empirical Mode Decomposition.
The empirical mode decomposition (EMD) first proposed by Huang et al. [1] is designed for the time-frequency analysis of real-world signals. By applying it, the signal can be decomposed into a number of oscillatory modes named intrinsic mode functions (IMFs). The IMFs are obtained directly from the data with no a priori assumptions regarding the data nature, making EMD suitable for the analysis of nonlinear and nonstationary signals. And then, these IMFs provide meaningful instantaneous frequency estimates through Hilbert-Huang transform. The time-frequency analysis via EMD has found a wide range of applications in signal processing and related fields.
sDL structure¶
Follows the standard sDL structure:
