Abstract
The method and system of the present invention uses synchronous rectification and frequency domain analysis to remove the need for calibration of the A/D and D/A components. It is applicable to any sensor based measurement in which either the sensor can be excited with an AC voltage or current, or in which the signal can be modulated with an AC voltage or current.
