摘要:
In an embodiment a method includes determining, for each capacitor element of a plurality of capacitor elements of a capacitor, an increase of a capacitance of a capacitor element caused by a decrease of a temperature of the capacitor and deriving a dew point from a temperature at which the increases of the capacitances or values corresponding to the increases of the capacitances exceed a predefined limit by generating a set of binary digits, each of the binary digits corresponding to one of the capacitor elements and indicating whether the capacitance of the capacitor element is within a predefined range, comparing sets of binary digits generated at different temperatures and determining a number of capacitor elements for which the corresponding binary digits of the sets are different and repeating the comparison for a sequence of sets generated at decreasing temperatures.
