Conclusions The EMD is obviously far superior when used for the right purposes. For outputs of linear, time-invariant systems the EMD is all but worthless, and time-consuming to calculate besides. For non-linear, non-stationary signals like so many signals are in the real world, however, the EMD is not only a useful method but possibly the only computational method of analysis. Taking our example of the ECG, until recently readouts of test data like that which we used were examined by eye and results were determined by estimation. Methods like this are not standardized and not very repeatable. The EMD may provide efficient handling of natural data. |
