Nevertheless, the major obstacle to the use of DVP is the noises that notably interfere with data interpretation. Ensemble empirical mode decomposition (EEMD), one of the two components of the Hilbert-Huang transformation, is an adaptive time-frequency data analysis method found to be useful for ...

An incoming oscillation, whose frequency during a brief reading interval is to be determined, is converted into a first pulse train of cadence f to be compared with the cadence f' of an astable multiv
The core idea of the HHT is to use Empirical Mode Decomposition (EMD) to decompose a time-series signal into Intrinsic Mode Functions (IMFs) with a trend and then apply the Hilbert spectral analysis (HSA) method to the IMFs to obtain instantaneous frequency data. The HHT assumes that any...
