Abstract
A method for determining a property of a medium, wherein an excitation signal is generated and transmitted into the medium, a measuring signal is generated from the excitation signal transmitted into the medium, the measuring signal is measured, an amplitude of the excitation signal and an amplitude of the measuring signal are determined, and the property of the medium is determined using the amplitude of the excitation signal and the amplitude of the measuring signal. To provide a method in which the accuracy of determination of the property of the medium is improved, the amplitude of the excitation signal is determined by digitizing the excitation signal and applying a lock-in method to the digitized excitation signal and determining the amplitude of the measuring signal by digitizing the measuring signal and applying the lock-in method to the digitized measuring signal.
