摘要： To determine the dependence of a first measured quantity (Y) on a second measured quantity (P) the second measured quantity (P) is periodically modified with a frequency (f0). The first measured quantity (Y), which changes accordingly, is measured. From the first measurement signal of the first measured quantity (Y) the components of the first measured quantity (Y) are determined with at least a plurality of frequencies. From the components determined in this way the first measured quantity (Y) is reconstructed by signal processing for at least a plurality of values of the second measured quantity (P).
