O
ur world is criss-crossed by RF signals since almost all our electrical and electronic equipment emits electromagnetic waves. These waves then interfere with each other to not-so-great results: we have all witnessed this first-hand when moving a radio under
power lines. The deafening 50Hz buzz that completely overwhelms the radio signal is a direct consequence of the power lines emitting powerful electromagnetic waves as the current alternates within the wires.

While merely irritating for the casual passer-by, EMI is a
serious concern for engineers in almost every application, especially in situations where signal integrity is vital, such as mission-critical military communications, fly-by-wire avionics and medical applications. In those situations, EMI can cause miscommunicated instructions, control signals and medical data, which could lead potentially fatal consequences. Tis is clearly not a desirable outcome and so a lot of work goes
into ensuring that electronics are EMI-compatible, i.e., not emitting substantial EMI flux, and being resistant to external EMI sources.
