The Hilbert-based time-frequency analysis has promising capacity to reveal the time-variant behaviors of a system. To admit well-behaved Hilbert transforms, component decomposition of signals must be performed beforehand. This was first systematically implemented by the empirical mode decomposition (EMD) in the Hilbert-Huang transform, which can provide a time-frequency representation of the signals. The EMD, however, has limitations in distinguishing different components in narrowband signals… 

Analytical mode decomposition of time series with decaying amplitudes and overlapping instantaneous frequencies

In this study, the recently developed analytical mode decomposition with Hilbert transform was extended to the decomposition of a non-stationary and nonlinear signal with two or more

On the difference between empirical mode decomposition and Hilbert vibration decomposition for earthquake motion records

In this paper, Empirical mode decomposition (EMD) and Hilbert vibration decomposition (HVD) are employed to process various different types of non-stationary and nonlinear vibration. The properties

Extraction of Instantaneous Frequencies and Amplitudes in Nonstationary Time-Series Data

A data-driven approach to time-frequency analysis that circumvents many of the shortcomings of classic approaches, including the extraction of nonstationary signals with discontinuities in their behavior is proposed.
