| Summary: | Заглавие с экрана At present, the method of linear prediction Coding coefficients is of great interest. Based on this model, systems for the analysis and synthesis of sound signals are built. The use of this model allows you to find differences and features when comparing audio signals. Its important advantage is the relative simplicity of parameter estimation using linear signal processing procedures. In this paper, we presented a method of linear prediction coefficients that allows us to analyze the ultrasonic signal from the point of view of its nonlinearity, which affects its time and frequency characteristics, in order to determine the dependence of the parameters of the method of linear prediction coefficients on the structural-phase state of the material under study - the titanium alloy VT6. |
