Verfahren zum Erzeugen von Quelltondaten

摘要

In the generating process, an analog or digital input signal is fed to a comb filter, passing only the basic frequency and its harmonic oscillations for generating analog or digital output signals. The reflating signal sections are separated from the output signal and recorded. To determine an interval of uniform analog signal portions, the analog signal is converted into a digital one by a Fourier transformation for generating second Fourier components. The phases of the latter are mutually matched, and another Fourier transformation is carried out. The periods of the peaks in the output data values are then determined.
