Hi all.
This is a question that should have an easy answer, I suppose. I know that a capacitor in a series circuit will store the average value of an arbitrary waveform, in that there will be equal area above the average value and below the average value. How would I extract this average value with analog circuitry?
Thank You Teece
Without knowing more detail, and depending on the range of voltage present across the cap, a buffer (op-)amp followed by a suitable low-pass filter is the way I'd start looking at it.
