Abstract

A circuit system for detecting a time-variable amplitude via an electric potential-difference to be detected. A first potential-difference detection device for detecting the at least one electric potential-difference and for outputting a first potential-difference signal, and a second potential-difference detection device for detecting the at least one electric potential-difference and for outputting a second potential-difference signal are provided. The first potential-difference detection device has a higher time resolution than the second potential-difference detection device, while the second potential-difference detection device has a higher amplitude resolution than the first potential-difference detection device.
