Dominant Frequency Extraction

Abstract

Time series are collected and studied extensively for the knowledge about the data source characteristics such as the trend or the spectral landscape. Some peaks in the spectral landscape correspond to dominant frequencies. The approach here is empirical: all time series are discrete and finite.

On the influence of input triggering on the dynamics of the Jansen-Rit oscillators network

“…The dominant frequency is usually the one that carries the most energy, which can be observed on a magnitude spectrum as the peak frequency [69,70]. Additionally, the fundamental frequency is the lowest frequency on a power spectrum with a peak [71]. The dominant frequency value is plotted as a function of the coupling term and external input in figure 18.…”
