Anyone out there know how to convert a bunch of analog voltage samples into a power reading? Do you just square the samples and average them?
Thank you.

Need more info; what, exactly, are you sampling, and how often relative to the frequency or period of what is presumably a periodic voltage waveform (or, if that's not a good assumption, just what IS it)? Also - what load does this voltage appear across? Purely resistive? If not, what?
I'm sure other questions could come up, but those will probably do for now...

Calculate the RMS value normally.
Has example..
