Detailed Description

A class to simulate EEG signals.

This class is writtern to provide a very basic EEG simulator based on creating normal distributed noise. It provides the possibility to increase the amplitude of this noise or add an offset to it. Additionally it is possible to and sine waves (frequency, amplitude and phase adjustable) to the simulated EEG. This can be applied to every channel individually while running using network communication.

Todo:

If needed: Provide the possibility to change the source-distribution during runtime.

Define and implement a configuration protocol.

Write an EEG simulator based on filtering rather than on adding just a Sine.
