Hey JackBruce
I got fed up with the crap the other posters wrote about your terminology,
and did not really see if anyone actually answered your question, Which, by
the way, Was very easy to understand. Ignore the other jackasses here, that
nitpick. They have too much time on their hands, i can see.

Question 1
The impedance of inductors and reactors is based on the varying signal
frequency, Weather it is offset by the DC component or not.
This answer assumes that you are not reaching the current limit of any of
the devices, naturally if the DC Current in the "L" Device saturates the
Flux medium ( air or iron) then you will get non linearities introduced,
Not sure what the limit on a "C" Device would be, probably current again.

Question 2
The link didn't work but most of the modern devices looking for peaks and
valleys work fine with a DC Offset.

2 questions about a fully DC Sine Wave....let's suppose you have a DC
Sine wave which varies from +5V to +15V peak-to-peak going into a load
with R, L, and C components.....

Question #1:
Is the load's impedance a function of R, L, and C (and wave frequency)
or is it simply just R (i.e. Z=R)? In other words does non-resistive
impedance (L + C) really only matter with an AC signal OR anytime
voltage varies periodically (even if it is all DC)?


Question #2:
Would a "regular" negative peak detector ciruit, like shown he

work for the DC Wave described? Will it output +5V or do negative peak
detectors only work for AC signals?

Thank you.
