- Abstract
- The results of spectral analysis of diagnostic signals obtained by the methods of functional electrophysical diagnostics with physical and mechanical tests of copper wire in tension. We used the methods of discrete Fourier transform, continuous wavelet transform and harmonic analysis. The specific spectral characteristics examined using temporal window functions Hann, Hamming and by shifting the Gaussian window parameters about the origin. The largest distortion of the diagnostic spectrum of the signal observed with Hann window. The results of spectral analysis have been modeled on the layout of the virtual appliance.
