This module is to amplify EMG signals in the PLUGSYS system. A floating input circuit is used to avoid hum and grounding problems. The filters are designed for EMG signals up to 10 kHz. The analog EMG 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 0.3 mV and 1 mV amplitude is incorporated for calibration. For EMG integration an envelope integration circuit is provided. This signal is also available on the front panel and on the PLUGSYS bus.
