Abstract: The invention relates to an electronic ballast having an interface having input connections (E1, E2) to which an impedance can be connected, wherein the circuit configuration is able, due to the variability of a frequency, to capture measurement values from which the resistance and the capacitance of elements simultaneously connected to the connections (E1 and E2) can be derived. Using both of said derived parameters, other parameters can be determined, particularly two items of information can be transmitted to the electronic ballast. An item of information to be transmitted is preferably a dimming duration, namely the duration for which a lamp connected to the electronic ballast is to be operated in dimming mode.
