Why a clinical neurophysiologist could wish to treat signals?

EEG, EOG, EMG or polygraphic recording can be sampled and manipulated by computers without loss of information.

The manipulation of these signals provides at least the following advantages:

• It is possible to edit, copy, backup or send data.
• Modifications of some measurements or methods can be implemented.
• Methods of analysis developed in other laboratories can be used without requiring specific equipment.
• New methods of analysis applied to Clinical Neurophysiology can eventually be developed.

Since neurophysiological signals have a lot in common with other signals, the knowledge of methods of treatment of these signals can contribute to the extraction of relevant information to our field.
