Abstract

Empirical mode decomposition technique is applied to noise removal of time-serial data obtained from coulostatically-induced transients(CITs).Different noises are added to the ideal CITs which is obtained by using randle equivalent circuit ,and then, the de-noising criterion in practice for CITs using the empirical mode decomposition is obtained. The result indicates that the most effective filtering under most cases should be that IMF1 and IMF2 together with 50 Hz component of the IMF4 were removed. In addition, such a de-noising criterion is also effective when it is applied to a real corrosion system.

Key words: empirical mode decomposition (EMD) coulostatic intrinsic mode functions (IMFs)
