THE ANTIALIASING FILTER PARAMETERS PROPOSITION FOR LABORATORY AND DOMESTIC EQUIPMENT APPLICATION OF POWER QUALITY MEASUREMENTS SYSTEMS
Journal Title: Metrology and Measurement Systems - Year 2007, Vol 14, Issue 3
Abstract
Digital signal processing exists in systems which perform the processing of power waveforms. All measuring devices that use digital signal processing and computing of its discrete spectrum should be equipped with an antialiasing filter which, unfortunately, creates errors in magnitude and phase spectrum responses. This paper discusses the spectrum distortion analysis of the power signals caused by antialiasing filter implementation in the analog-digital signal processing system paths. The paper is a continuation of problems included in [1]. On the basis of the same research methodology the article completes research carried out in [1] about a real input signal model. Thus, it has been possible to describe antialiasing filter parameters in power quality measurement systems for laboratory and domestic applications.
