Abstract
Algorithms for time-finite signal restoration are developed in view of feasibility of the pulse characteristic of processing devices. Functions with a lower level of side lobes than in the known functions for single-channel and two-channel restoration systems with using signal samples and time-finite signal derivatives are synthesized. Optimum functions are calculated and quasi-optimum time-finite synthesizing functions of the interpolation algorithm are proposed, which allow consideration of time constraints of initial signal realization and feasibility of the processing devices. It is found that the proposed algorithms will reduce the root-mean-square error of interpolation by 45
