Wavelets son funciones que oscilan (wave) y decaen (lef) a cierto número de desvanecimientos, las cuales fungen como filtros para capturar componentes de alta frecuencia con duración de corto tiempo y componentes de baja frecuencia que ocurren en periodos de mayor tiempo. Contrario al análisis de Fourier, el análisis por wavelets permite analizar una serie de tiempo en el espacio tiempo-frecuencia. Su principal flexibilidad es que permiten estudiar fenómenos temporales no estacionarios y de variación en el tiempo.

| selected citations These citations are derived from selected sources. This is an alternative to the "Influence" indicator, which also reflects the overall/total impact of an article in the research community at large, based on the underlying citation network (diachronically). | 0 | |
| popularity This indicator reflects the "current" impact/attention (the "hype") of an article in the research community at large, based on the underlying citation network. | Average | |
