EMI (Electromagnetic Interference)

Electromagnetic interference (EMI) is a radiated disturbance that affects an electrical circuit by electromagnetic induction or electrostatic coupling.  The disturbance can result in degraded performance or even failure in the receiver circuit.  In the case of a data path, effects can range from increased error rate to total data loss.  In medical or mass transit applications, EMI can cause extreme damage or failure and even be life-threatening.

 

We have experience characterizing environmental low- and radio-frequency electromagnetic fields.  We have measured the effects of EMI at client sites and we have authored EIR chapters concerning the impact of EMI radiated from client projects.  Below are some of our EMI-based projects.
