How does crosstalk contribute to the attenuation of the aggressor signal?

Answer

Energy transferred from the aggressor trace to the victim trace is energy that did not reach the intended destination.

Crosstalk involves the transfer of energy from the aggressor trace's electromagnetic field onto an adjacent victim trace, thus reducing the total power successfully delivered by the aggressor signal.
