Abstract: The properties of slippery discrete integrating correcting filtering relatively suppression of systematic and accidental components of instrumental error are researched by the way of computer modeling.

Keywords - information-measuring systems; discrete averagings; digital measurement; digital processing of signals; instant value; quantization noise.

Introduction. The purpose of the study is the control and increase of a management efficiency of objects of development and consumption of electric energy by transformation and digital processing of not sinusoidal electric signals, working out and application of methods and means of increase of accuracy of digital processing of the measuring information. In any case process of creating own software is important in order to simplify, reduce time and direct financial expenses for its working out.

Problem decision. Now in connection with development of computer facilities the wide circulation is received algorithmic by methods of increase of accuracy of measurements [1]. They are based on reception in the course of functioning of information-measuring systems of the additional information, allowing excluding influence of errors on result of measurement.

The additional information can be received for the account of presence structural, time or structurally - time redundancy of information-measuring systems. Distinctive feature of use of algorithmic methods is possibility of increase of accuracy of results of measurements without improvement of metrological characteristics of initial measuring devices and systems [2].

During drilling of oil wells it is measured some parameters as the temperature, pressure, density etc. all these parameters process to receive further the certain information. As results of the experimental measuring data received from reservoirs as jammed and it is necessary to execute a filtration of these data before to make their processing. Adverse influence of non-sinusoidal for work of networks, electric  equipment and electro-receivers consists in the following: there are additional losses in electric cars, transformers and networks, and also additional deviations of pressure; service life of isolation of electric machines and devices is reduced; work of devices

of automatics, mechanics and communication worsens.

Сonclusion. Thus, the offered system approach to creation of information-measuring systems of considered appointment consists in the cumulative analysis of processes of measurement and a correcting filtration for the purpose of achievement of the balanced indicators of metrological, structurally-algorithmic and functional efficiency of developed means.
