Default Re: Simple Low Resistance Measurement

Synchronous detection of a single frequency that is not associated with the mains or other local signals was an excellent method for extracting a low level signal from a very noisy environment. We used an AD630 for continuous large battery ESR measurement in on-line battery systems.
