RECONSTRUCTION OF ANALOG SIGNALS AND CHOICE OF SAMPLING RATES IN TELEMETRY

Abstract

The reconstruction of the form of analog signals by samples by means of linear filtration is considered. Precision criterion - mean square reconstruction error and the maximum reconstruction error probability. Linear filters (reconstructing functions) of increasing difficulty are considered together with an optimal filter. A signal model is introduced by means of large set of correlation functions. The calculations of reconstruction errors are carried out for different reconstructing functions. The tables and the figures allow to determine reconstruction errors, to estimate the necessity of decreasing complexity of the filter and to choose the type of filter. The results of calculations and the recommendations of choosing the sampling rates of the sensors are made in the paper can be used by the experimenters and specialists in telemetry.
