Application of the empirical mode decomposition and Hilbert-Huang transform to seismic reflection data

Published: 02 March 2007
Geophysics (2007) 72 (2): H29–H37.
...) which combines with the Hilbert transform as the Hilbert-Huang transform (HHT). The EMD empirically reduces a time series to several subsignals, each of which is input to the same time-frequency environment via the Hilbert transform. The HHT allows for signals describing stochastic or astochastic...

... for nonstationary signals and the creation of spurious harmonics for nonlinear signals. We present an open‐source implementation of the Hilbert–Huang transform ( HHT ), an alternative spectral method designed to avoid the linearity and stationarity constraints of Fourier analysis. The HHT defines instantaneous...
