ABSTRACT:
A self-calibrating sensor system is disclosed wherein a processing circuit, normally including an amplifier, receives the output of at least one sensor to develop a processed sensor signal. To compensate for errors (gain error, etc.) in the processing circuit, the preferred embodiment includes a microprocessor which senses certain signals developed by the processing circuit, computes correction factors based on the sensed signals, and then modifies the processed sensor signal so as to substantially eliminate the effect of the errors.
