EEG-SMT Signal merger

[soha89]

Hello everyone! I have some questions about the EEG signal. I have done the signal spliting from the device in Matlab/Simulink, and now I don't know how to merge the signals from low and high channels. 1. What have to I do to connect them and how I have to change the binary signal to normal wave? 2. This is a stupid question, but how many bits should I set to Input Buffer. 65536, or 512? I think that first number is too big. I'll be glad for any advices.

Here is the picture of my signals.

First of them is an original not separated signal. Second is detecting the sync data, what means the new package was sent. The others is: channel 1(with connected electrodes)-high, channel 1-low, channel 2(without electrodes)-high, channel 2-low. As you can see, the signals from the electrodes was shifted in a way that they are all showed at the same time.

Hey there,

The EEG module and the demo are just an implementation of the OpenEEG design. The example itself is based on firmware 2 of the specified by OpenEEG community here: http://openeeg.sourceforge.net/doc/modeeg/firmware/modeeg-p2.c.

For software related question I recommend you to refer mainly to the documentation on the official OpenEEG web-site: http://openeeg.sourceforge.net/doc/.
