Abstract
A device and a method for determining pressure fluctuations in a fuel supply system provide two signal filters to enable determining as much information about pressure fluctuations as possible with minimal sensor use. A sensor signal which is characteristic of a pressure in the area of a fuel injector is filtered using the two filters, which have filter characteristics that differ from one another.
