During the spectral analysis of scanned signals with the aid of the discrete Fourier
transformation, a so-called frequency resolution (Df) results, Df being =fA/N,
independently of the scanning frequency (fA) and of the number of measurement
values used (N).
The spectra of scanned signals are only defined for frequencies, which are an
integer multiple of this frequency resolution.
