# EFD
Empirical Fourier decomposition: An accurate signal decomposition method for nonlinear and non-stationary time series analysis

Segm_tec.m: This function is used to implement the improved segmentation technique 

EFD.m: This function is used to construct a zero-phase filter bank

plotbounds.m: This function is used to plot the detected boundaries under the Fourier spectrum 

EFD_test.mlx: a sample implement for the EFD

EFD_TFR_test.mlx: a sample implement for the TFR of EFD

Plot_TFR.m and nspplote.m: This two functions are used to plot TFR

IFIA.m: This function is used to obtain instantaneous frequencies and amplitudes
