In this article we compare the cross-correlation and breakfinder techniques applied to the measurements of redshifts from low-resolution spectra. We assume spectra obtained from multinarrowband ...

Since the 1990s, cross-correlation has been the primary method for reducing or removing the effect of instrument phase noise. What is Cross-Correlation?

The E5052 instrument uses a cunning cross-correlation technique enabling it to measure phase noise levels below that of its own internal signal source.
