Uncertainty of measurement for a wavelet analysis of the data
Yu.D. Volkov · Russian Internet Journal of Industrial Engineering · 2014
The article presents a model of experiment data pro-cessing, which reflects the uncertainty in measurement. For the processing of uncertainty is proposed arithmetic fuzzy FN - numbers . The graph of the function accesso-ries FN - numbers has the shape of an isosceles triangle. The scale of the digital measuring instrument is repre-sented by fuzzy function on the set of real numbers. The fuzzy experimental function is expanded on the Haar's base with a quick wavelet transform. This approach al-lows estimating the uncertainty not only in measure-ment, but also in subsequent computer calculations with wavelet analysis of experimental data.
