The Time and Frequency Domain Measurements of the Magnetic Fields Emitted by Video Display Terminals

Abstract

This paper presents the results of measurements of the magnetic fields generated by video display terminals (VDT). For a complete field characterization the time and frequency domain measurements of the field are made at some distances from the screen. There were performed comparative measurements by using a few sensors.

Acquisition and Analysis of Biomedical Signals in Case of Peoples Exposed to Electromagnetic Fields

“…In the figure are highlighted the disturbing couplings through electric field (capacitive coupling) from the power line to the three main "vulnerabilities": the patient, the connecting path and the amplification module of the measuring device [14]. Also, the interaction of magnetic field, H, generated by power line current, I, in the loop formed by patient electrode 1-wire 1-amplifier, PA -wire 2-patient electrode 2, is represented.…”
