Cyton board channel data samples appear to be DC?
I have a question now. I got the data from CYTON plus WIFI board and the same rate is 1000HZ or 500HZ. The method of collecting data is OPENBCI GUI software. After opening it with MATLAB, I found that the data of each channel are all in the thousands or tens of thousands. There is not even a negative value. I would like to ask, when CAYON collects data, on what basis is it counting? Why are the data values collected from each channel so different? And it seems that they are all DC data, without any negative values of AC components?
