Estimation of Measurement Window Width by Interpolation Based on Wavelet Coefficients – Case Study

Tomasz Tarasiuk
Abstract:
This paper deals with the problem of reliable width estimation of measurement window. The simple method is detection of zero-crossing moment of given signal by analysis of sample polarisation changes. But the method is sensitive to waveform distortions, especially analysed signal multiple zero-crossings. So, the idea of implementing discrete wavelet transform for risk reduction of measurement results corruption by the higher frequency phenomena has been proposed and preliminary tested [1]. In this paper, the concept has been further developed, especially the analysis of real voltage with multiple zero-crossing has been carried out.
