Wavelet-bounded empirical mode decomposition for measured time series analysis

•We describe a new method for optimizing EMD using wavelet transforms.•The method drastically reduces the effect of mode-mixing.•The method’s success and robustness is studied using a two-component signal.•We extract IMFs that representative of the NNMs for a beam with local nonlinearity.•The IMFs a...
