Empirical mode decomposition: a method to reduce low frequency interferences from surface electroenterogram.

abstract：:The aim of the study was to investigate the effect of signal length on the performance of a signal source separation method, independent component analysis (ICA), when extracting the visual evoked potential (EP) lambda wave from saccade-related electro-encephalogram (EEG) waveforms. A method was devised that enabled t...
