You have a 10V Dc ssignal with a superimposed 5V p-p signal.
The load's impedance to DC is determined by the load's DC resistance (steady
state )
The load's impedance to AC will be determined by its R (ac not Dc) ,L,C
combination (steady state)
The two are different and independent values.

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.
