Agadzhanyan A. Application of temporal frequency methods for processing unsteady signals in real time.

The dissertation seeking a scientific degree of the candidate of engineering science in specialty 05.12.13 - radio engineering devices and tools of telecommunications. - Odessa National Polytechnic University, Odessa, 2011. The dissertation's dedicated to analysis methods of radio technical devices dynamical conditions, analysis methods of unsteady signals, based on frequency-temporal characteristics. The connection between temporal, frequency and frequency-temporal signal processing methods is defined. The opportunity and advantage of using bypassed in these methods is shown. The mathematical model, using dynamic transfer coefficient method is constructed for solving the problem of dynamic distortion determination in digital narrowband circles, when the signals from amplitude modulation and frequency modulation are passing. It's shown that on the basis of developed wavelet-transform method the definition of pathology for cardio signals is possible. The probabilistic parameters of selective circle are defined. The application fields for each method were clearly defined, while comparing frequency-temporal analysis algorithms. The dynamic distortion corrective method, which is based on the dynamic transfer coefficient method, is suggested. The influence of input signals frequency alteration comparatively resonance frequency to amplitude, frequency and phase of outline output signals is analyzed. Keywords: dynamic transfer ratiocircuit, no stationary signals, wavelet, wavelet dynamic-characteristic.
