Abstract

The following paper is a presentation of the digital system used for measuring interference in low frequency range that occurs in low-voltage power supply. It discusses how the hardware of the system, controlled by graphical programming environment LabVIEW v.4.0 National Instrument, has been realised. Furthermore, it presents basic functions, which the virtual part of the system performs. The paper gives special attention to the methods used in determining quantities, which describe deterministic as well as stochastic types of interference. Additionally, the paper defines the conditions deciding about inaccuracies of the evaluation of estimators.
