signal reconstruction, nonuniform samples, oversampling.


Computer simulation is used to compare errors at reconstruction of signals with finite number degrees of freedom in the presence of additive amplitude noises for two reconstructing algorithms when samples are displaced relatively to uniform positions. Plots, reflecting noise amplification coefficient versus the degree of sampling nonuniformity, are built. It is shown that oversampling procedure essentially decreases reconstructing errors and makes them weakly dependent on degree of nonuniformity.
