WebApr 1, 2024 · ERP and TF analysis comparison. On the left column, the figure shows a simulated EEG signal across five trials. The trials were simulated to have a non-phased-locked 6 Hz response around 0 ms and a phase-locked 10 Hz response around 500 ms. The middle column shows the average ERP of each trial and all previous trials. WebActual EEG signals can be seen as a mixture of different frequencies. As shown below, when mixing 2Hz, 10Hz, and 20Hz signals, a complex signal may be observed. If we run a simple Fourier Transform on this data, we …
