This module amplies ECG signals. A floating input circuit is used to avoid hum and grounding problems. A bar graph display permits visualization of the ECG signal. The filters are for heart rates up to 1000 beats per minute. Both outputs can be used for recording on a chart recorder or for data acquisition. A square-wave signal generator with amplitudes of 0.3 mV and 1 mV is incorporated for calibration.
