Voltage adder



I've got a +2 to -2 volt AC signal and an A/D board that reads 0-5V. Can
anyone with more electonic experience than I tell me the best way to add
2.5V DC to the signal so that it is centered in the A/D board range? I seem
to recall there is a standard way to do this but don't see it right off in
the books available to me right now.

Thanks,
kyle
