Abstract
Circuits are provided for detecting an electrosurgical unit signal. An example circuit includes: a filter configured to process a floating ground signal associated with measuring a bio-potential signal of a patient, and a detector configured to output a sensing signal based at least in part on the floating grounding and the Earth ground for detecting an electrosurgical unit signal.
