<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">What is signal and what is noise depends on your question. E.g. If you test amplifiers the line frequency (50Hz or 60 Hz) may be your signal and the EEG is
noise. If you look at a standard EEG recording, the EEG will be the signal and the line frequency is noise. If you looked at evoked responsen, the correlated EEG is the signal and the uncorrelated EEG is part of the noise.
