Abstract
The paper presents the results of computational experiments on the decomposition of electrometric observation data on empirical modes using the RIMF program. This modification of the Empirical Mode Decomposition method (EMD) is geophysical data processing oriented. Of hers distinctive feature is the use of harmonic (potential) functions when constructing signal envelopes instead of cubic splines traditionally used for this purpose. EMD is a highly adaptive method for analyzing nonlinear and non-stationary signals. It can be used to highlight the information component in the results of electrical profiling. To clarify the effectiveness of using EMD in monitoring observations, calculations were performed for two stages of measurements: spring and autumn.
