7. Conclusion

A methodology for modeling and simulating the EMC behavior of an equivalent circuit on a mixed-mode electronic board is developed. The general theoretical concept used to develop the EMC analysis approach is based on the mathematical theory of a Gaussian distribution of random variability representing the circuit parameters. The methodology for functional modeling of the PCB with its specifications and parameters is developed, taking into account the interaction with its environment. The circuit's conducted EMC emission model is explained, along with the spectral specifications of the test signal with a periodic trapezoidal waveform. The PCB's conducted EMC susceptibility model is based on definitions of the amplitude classification margins and characteristic frequencies of the observable signal spectrum. EMC, IS and IP simulation results for our circuit case study are discussed on the...
