4. Electromagnetic compatibility analysis

When a number of sub-systems are designed or need to be combined in order to implement a large system or installation, an overall EMC analysis must be carried out with regard to specifications concerning the device as a whole. This approach requires knowledge of the emission levels of the subsystems, their susceptibility levels, and the modes of coupling and attenuation of intersystem disturbances. This information is often acquired experimentally after characterization, but we have seen that it can also be predetermined by simulation.
