- Abstract
- The method of frequency-time analysis of signals of electrophysical diagnostics is described and results of application of the method are given at tests on destruction of steel EI847. To analyze the results of the processing of diagnostic signals, a window Fourier transform with a Gaussian function was used. An alternative method is presented for windowing based on the construction of a signal power spectrum using the autocorrelation function. The design of the developed device Spectroelph for electrophysical diagnostics of materials is presented at tests on tearing machines with a horizontal way of loading.
