Unfortunately, it is not superposition that must be considered.For a wire, when skin effect occurs, the current will be excluded from the wire interior, in gradations of course.. So, a skinning current will have no internal inductance, hence no energy storage. Whereas, the lf info does not, and does have internal energy storage.
If an audio lf signal is pulled across zero by a hf signal, the internal stored energy will be pulled out by the slew rate of the hf information..it is not clear yet if that released energy is consumed in the re-distribution of the current density profile, or if it reacts externally, possibly time shifting the leading and trailing edges of the hf information, thereby blurring the interpreted soundstage. That would require time shifts in the 5 to 20 microsecond realm.
See, that wasn't so hard, now was it??
