EMI filter design in Pspice

An application of the Pspice software is discussed through an example of an electromagnetic compatibility(EMC) test. Firstly the electromagnetic interference(EMI) signal is modeled and analyzed through the software, and then a low pass circuit is designed and emulated by the software. The EMI signal and the used signal that passed the low pass circuit are compared by the Pspice software. It is a real example of Pspice software used in EMC design, so it is much valuable for the design of EMC.
