The following plots show different kinds of simulated time series.
- the left plot shows the ongoing time series
- the right plot shows the corresponding power spectrum
First, we have an oscillatory signal, showing rhythmic activity:
Next, we will explore some aperiodic signals.
First, white noise, defined as having equal power across all frequencies (a flat power spectrum):
Next, we have pink noise, which has a pattern of decreasing power across increasing frequencies:
Finally, we have brown noise, with has a steeper drop-off of power across increasing frequencies:
Next up, we have 'combined signals', which are a combination of periodic and aperiodic components:
Finally, we have a bursty signal:
