Abstract:
1. A circuit system for detecting a time-variable amplitude of at least one electric potential-difference to be detected, comprising: a first potential-difference detection device for detecting the at least one electric potential-difference and for outputting a first potential-difference signal; a second potential-difference detection device for detecting the at least one electric potential-difference and for outputting a second potential-difference signal; wherein the first potential-difference detection device has a higher time resolution than the second potential-difference detection device, and wherein the second potential-difference detection device has a higher amplitude resolution than the first potential-difference detection device, the circuit system selecting one of the first potential-difference signal and the second potential-difference signal, based on whichever potential-difference signal has a higher precision, and outputting a control signal using the selected potential-difference signal.
