[RFI] TI - Power Line Communications?

[Hare, Ed W1RFI]

I'd think that the spectral  purity of the signal is no more dependent on component aging than any other technology. Modern capacitors, for example, tend not to change value much with time.  They can fail, thus degrading filtering, but that could be a problem with any technology.

Thank you for that perspective.

That is encouraging news.

Any sense as to how dependent the spectrum purity is on age and environment-degraded components, e.g. bypass or PS capacitors?
