Method development and investigation for the optimum linear filtration under conditions of the random discretization of signals

By Prokhorenkova Alla Tikhonovna

Abstract

Impulse systems with the random discretization of signals with the presence of the additive interference are considered in the paper aiming at the development and investigation of effective methods and algorithms for the linear filtration of the legitimate signal, suppressed by the additive interference under conditions of the random discretization of signals. The practical application of the methods developed is also the aim of the paper. As a result the system of equations, describing the optimum characteristics of the linear digital filter has been obtained as well as the analytical description of the optimum linear analogous filter. The theorem, making it possible to find the solution for the system of equations, describing the characteristics of the optimum linear digital filter, in the particular form has been proved. The consequence, making it possible to determine the order of the optimum digital filter, has been proved. Methodologies for the parameter determination of optimum linear digital and analogous filters have been developed as well as the software for digital filters. The automated system for the parameter control of gas analyzers with the digital filtration block has been introduced into operation. The digital fietration block has been introduced into operation. The digital fietration block, introduced into the software composition, makes it possible to increase the accuracy of the gas analyzer scan.
