摘要：
In this article the application of the Hilbert transform to correlation time delay measurements of two stochastic signals is presented. The statistical errors of estimation using direct cross-correlation and cross-correlation in which the one signal is replaced by its Hilbert transform are compared. For the chosen model of signals the range of signal to noise ratio is obtained, where the considered methods have less random error of time delay estimation.
