Concepts Of EMI and EMC
Noise is any electrical signal present in a circuit other than the desired signal. This definition excludes the distortion products produced in a circuit due to nonlinearities. Although these distortion products may be undesirable, they are not considered noise unless they are coupled into another part of the circuit. It follows that a desired signal in one part of a circuit can be considered to be noise when coupled to some other part of the circuit. An electromagnetic disturbance is any electromagnetic phenomenon which may degrade the performance of a device, or an equipment, or a system. The electromagnetic disturbance can be in the nature of an electromagnetic noise, or an unwanted signal, or a change in the propagation medium itself.
