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.
