Conventional signal decomposition methods, such as the fast Fourier transform, widely used in signal analysis based on time series techniques, have some issues when analyzing nonlinear and non-stationary signals, in addition to difficulties in detecting low-order frequencies.Results: To overcome these limitations, alternatives such as empirical mode decomposition and one of its variants, called ensemble empirical mode decomposition, have been developed.Conclusions: In this study, the results obtained through the aforementioned techniques were compared, revealing the impact of nonlinear methods on the reconstruction of brain activity. electroencephalogram, empirical mode decomposition, epilepsy, instantaneous frequency, intrinsic mode functions, methodology, nonlinear, non-stationary, oscillation modes, seizures. 2024 artículo científico 0121-750X https://www.redalyc.org/articulo.oa?id=498880092002 https://www.redalyc.org/journal/4988/498880092002/ https://www.redalyc.org/journal/4988/498880092002/html/ https://www.redalyc.org/journal/4988/498880092002/498880092002.epub https://www.redalyc.org/journal/4988/498880092002/movil 10.14483/23448393.21311 en http://www.redalyc.org/revista.oa?id=4988 Ingeniería application/pdf Universidad Distrital Francisco José de Caldas Ingeniería (Colombia) Num.2 Vol.29
