An Automatic Device for Testing Medical Electrodes

The resolution of medical electrographic apparatus� es depends on the human biopotential electrode noise and noise of the monitoring system. Noise of the monitoring system within certain fre� quency ranges is reduced to 10�100 nV. This reduction is due to reduction of electronic circuitry noise. Human biopotential electrode noise should also meet stringent requirements. In ideal case, the monitoring system noise is negligi�
