Time:	Wednesday, May 17, 14:00 - 16:00
Presentation:	Poster
Topic:	Signal Processing Theory and Methods: Non-stationary Signals and Time-Frequency Analysis
Title:	On the Influence of Sampling on the Empirical Mode Decomposition
Authors:	Gabriel Rilling, Patrick Flandrin, ENS Lyon, France
Abstract:	The rationale underlying the nonlinear Empirical Mode Decomposition method is intrinsically a continuous-time approach. The method can however only be applied in practice to discrete-time signals. EMD is obtained through iterating a basic nonlinear operator for which we derive an upper bound for the effects of sampling. Finally the effects of sampling for a complete EMD are assessed using the knowledge on the basic operator.
