A Methodology to Assess Immunity to Radiated Disturbances of Fpaa-Based Front-End Devices for Electrocardiograph Signal Monitoring

摘要

The paper is focused on the assessment of the functional immunity of field programmable analog arrays (FPAA) circuit configured to operate as front-end elements to be used in electrocardiography (ECG) signal conditioning, and on the investigation of the possible effects of radiated electromagnetic disturbance in the range from 250 MHz to 3 GHz, on the parameters of the ECG signal. The research is carried out with a methodology which relies on typical ECG signal and both time and frequency domain analysis. Results show that under specific amplitude and frequency conditions, the disturbance can indeed interfere with the normal operation, leading to erroneous diagnosis.
