A raw evoked potential is often difficult to distinguish from the ongoing EEG signal due to the presence of random noise. An average evoked potential (AEP) is obtained by averaging several epochs of the EEG signal following a stimulus, which enhances the signal-to-noise ratio, making the evoked potential more observable.
