This module is for amplify EEG signals. A
floating input circuit is used to avoid hum and
grounding problems. The filters are for EEG
signals up to 70 Hz. The analog EEG signal is
available at a BNC connector on the front
panel and also internally on the PLUGSYS system
bus. Both outputs can be used for
recording on a chart recorder or for data
acquisition. A square-wave signal generator
with amplitudes of 50 μV and 100 μV is incorporated
for calibration.
