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=3DR)? 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 here:~> This sounds like a Clamped Up Pulsating DC Waveform rather than a Sinewave.
In other words a true rms sinewave (as mentioned) equaling =3D [(-5 ~ 5)pp=
- 10vdc clamper =3D 5 ~15 VDC] About the detector if you can set it's values, VCC to Gnd etc. (also mentioned) to detact the Less Positive
