Abstract
An interference signal measuring facility is in a differential voltage measuring system with a signal measuring circuit for measuring bioelectric signals with a number of useful signal paths, each with a sensor electrode. In an embodiment, the interference signal measuring facility has an additional sensor lead for each sensor electrode each of which is electrically connected to a ground connection of a supply lead of a sensor electrode; and a measuring amplifier circuit, for each sensor electrode connected to the additional sensor lead via an electrical resistor, configured to detect a change in electric potential occurring on the sensor lead and to determine an electrode reference interference signal therefrom. Also described is an interference signal compensation facility; a differential voltage measuring system; and a method for generation an interference-reduced biological measurement signal are described.
