WebOct 19, 2024 · For the case of common-mode noise, it can be simulated by adding a voltage source to the return path. A filter is adequate when both types of noise are sufficiently attenuated, so try to avoid focusing completely on one type of noise and neglecting the other. Ideal vs. Real EMC Filters WebFigure 8 shows the CM and DM noise using an LTspice FTT plot measured from the LISN terminals V1 and V2. To reproduce the arithmetic operations shown in Figure 6, the V1 and V2 are subtracted and multiplied by 0.5 for the DM noise, and V1 is added to V2 with the result multiplied by 0.5 for the CM noise.
