ABSTRACT

ABSTRACT

The dependence of signal-to-noise ratio on the number of scans in covariance spectroscopy has been systematically analyzed for the first time with the intriguing relationship of SNRcovân/2, which is different from that in FT2D spectrum with SNRFTân. This relationship guarantees the signal-to-noise ratio when increasing the number of scans.
