EMD decomposition in Huang transform
4.0
This is a divided IMF EMD program, Hilbert-Huang transform (HHT) is a new technology of non-stationary signals processing, this method is called by the empirical mode decomposition (EMD) and the Hilbert spectral analysis consists of two parts. Arbitrary Nonstationary signal first treated after EMD method is broken down into a series of characteristic scales with different data series, each sequence is called an intrinsic mode functions (IMF), and Hilbert spectrum analysis on each IMF component to get the corresponding component of the Hilbert spectrum, summarizing all the Hilbert spectrum has been the original signal spectrum. This method is essentially for smooth processing of non-stationary signals, signal fluctuations or trends exist in different scales step by step factoring out end of instantaneous frequency and energy to represent the frequency content of the original signal.
