Abstract

A differential voltage measuring system is described. The differential voltage measuring system has a signal measuring circuit for measuring bioelectric signals, and an interference-signal measuring circuit coupled to the potential of the differential voltage measuring system and electrically connected to a fixed reference potential. In this case, the interference-signal measuring circuit is designed for measuring a current flowing from the potential of the differential voltage measuring system to the fixed reference potential. A differential voltage measuring system with an additional path is also described. Furthermore, a differential voltage measuring system with an averaging potential measuring method is described.
