How Does EMI Affect Various Electronic Systems? (Part 2) (Download)

Read this article online.

In Part 1, we discussed electromagnetic interference (EMI) in spacecraft electric propulsion systems (EPS), communications equipment, radar, navigation systems, IFF systems, and wireless-power-transfer designs. Part 2 again addresses how EMI is defined and looks at its effects on PCBs and other digital systems, plus presents one method to reduce EMI.   

EMI is essentially a disturbance caused by an electromagnetic field that prevents the proper performance in an electrical/electronic system. EMI can emanate from both natural and man-made sources, for example, the Sun’s or the Earth’s magnetic fields.
