Comparison of two algorithms of realizations recovery by arbitrary reading number

Usually realizations recovery by arbitrary readings number is carried out with using function sinc and function of the conditional average. There are considered these two recovery algorithms using the same number of readings from the right and the left in regard to a recovery interval. The gaussian process with the zero average and unit variance is chosen as a process subjected to discretization and following recovery. It is shown that in large spectrum limitation the both algorithms give the same recovery error. However with the increase of the spectrum limitation frequency the recovery error using the sinc-function, is approached to a nonzero limit whereas the recovery using the conditional average, has the zero asymptote.
