EEG Toy Generator
This educational application generates EEG (electroencephalography) data as if they were recorded on a human by means of one electrode. It also may show the (cumulative) average spectra of the signal and an ERP (event-related potential) template superimposed to each epoch, along with the ensemble average ERP.
As the number of epoch augments, the average spectra converge to the generating spectra and the ensemble average converges to the ERP template.
