Hi Chris,

The answer is yes, there's a highpass filter there. :-(
However, consider trying the highres EEG design I just posted. It
should work for EMG and ECG as well as EEG without any
modifications. :-)
Since you are a biomedical engineer: Do you have any input-stage
designs to share that would pass IEC60601-1 compliance tests?
Joerg Hansmann has designed a nice circuit that looks very promising
in simulation. What is your opinion on it? (Steve, if you are reading
this, feel free to give your opinion as well) It is uploaded as
a .gif to the same directory as the hires-eeg.

Andreas
