Discussion of Electromagnetic interference
■Electromagnetic interference (EMI), also known as radio frequency interference (RFI) when in radio frequency, is caused by undesirable radiated electromagnetic fields, or conducted voltages or current from an external source, which interferes with the safe and stable operations of an electronic device. This interference can come from any artificial or natural object that carries rapidly changing electrical currents, like an electrical circuit, the sun or the Northern Lights. This disturbance or interference may interrupt, obstruct, limit or degrade effective electronic device performance. These effects can range from simple performance degradation to a total loss of data or, at worst, device failure.
■To avoid these potential performance issues, electronic device design commonly incorporates several materials that promote stable performance in the presence of EMI.
■An illustration of this design is the specific installation of a shielding enclosure and grounding gaskets shown in Figure 1.
●ORING OF EMI
■Electromagnetic interference can come from a number of different sources and be categorized in a number of different ways. EMI sources can be natural or man-made. They can be categorized by duration like continuous interference or impulse “noise” (noise meaning interference), or categorized by bandwidth (narrow or broad band).
■How does EMI happen? Normally EMI occurs from a coupling mechanism (or path) caused by one of the following models. The general theory of coupling is shown in Figure 2.
