Dynamic signals filtration in high level noise condition

Abstract

To examine the opportunity of measuring bulk solids consumption the experimental setup was developed. The main problem was the presence of a non-harmonic signal at the output. Almost always there are some difficulties to build measuring circuits using non-harmonic signals. It is necessary to use one of the approximation methods to receive a wanted signal without noise. For this purpose, the local approximation method was chosen. The developed technique confirmed its positive aspects and allowed to solve the questions that were posed before the experimental setup.

Dinaminių signalų filtravimas esant aukšto lygio triukšmui


Santrauka


Biriųjų medžiagų išeigos matavimo galimybėms tirti buvo sukurta eksperimentinė įranga. Pagrindine problema buvo neharmoninis signalas matavimo įtaiso išėjime, apsunkinantis matavimo grandinių kūrimą. Naudingo signalo filtravimui nuo triukšmo būtina taikyti aproksimavimo metodus. Tyrimui pasirinktas lokalaus aproksimavimo metodas. Sukurta metodika patvirtino savo privalumus ir gebėjimus spręsti tiriamai eksperimentinei įrangai iškeltus uždavinius.


Reikšminiai žodžiai: filtravimas, trukdžiai, lokalaus aproksimavimo metodas.

Keyword : filtration, noise, local approximation method
