摘要：

A number of commercially available digital correlators is discussed with respect to algorithms, systematic errors, and statistical errors. Special attention has been paid to the determination of an influence of the temporal integration of measured signals on autocorrelation functions measured in digital correlators. A calculation of the standard deviation for statistical errors in correlation estimators has been performed. The result is compared with the experiment. Favorable noise properties of the multiple-tau correlator which have been reported in the literature are not confirmed. (C) 1999 American Institute of Physics. [S0034-6748(99)01012-6].
