A/D power formula

[[email protected]]

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...
