文摘：The characteristics of interpolators based on "moving" interpolation by the Lagrange polynomial are considered. Relationships for the sampling functions, their spectra, and also the time- and ensemble-averaged variances of signal reconstruction errors are presented. A "sampling theorem" for signals with various differential properties is formulated. The noise-immunity of the interpolators is estimated.
