Jitter in sampling and restoration of gaussian random processes at the output of linear parametric system

On a basis of conditional mean method there is represented description of jitter in sampling and optimal reconstruction of nonstationery process at the output of the first order parametric RC system under the influence of white noise. We consider two kinds of system parameters modification: linear and sinusoidal ones. Reconstructing functions are defined, and reconstruction errors are estimated for both cases. Jitter effect is described by random value with beta-distribution.
