retroactively separating such interfering noise to better identify the correlation maximum
caused by the leak.
3.2.6 Correlation Spectrum
Figure 27 Correlation Spectrum
The correlation spectrum is a combination of the signal spectra of the two sensors, which is
used for the correlation on the pipeline between the two sensors. In these common spectra, it
may be possible to identify the influence of noises not related to the leak (e.g., electrical
noise or pumps) on the correlation result (see also 3.2.4 Correlation Context Menu).
