Originální abstrakt

Analysis of complex vibrations normally takes the form of presentation of components frequencies related to their amplitudes, or a presentation of how the amplitude of specific signal varies with time. For a full understanding of vibrations, generated by a passing train (acts by generally non-stationary signals), is needed a simultaneous three-dimensionally (or contour) presentation, showing the occurrence of different frequencies related to time. Page distribution presents a suitable transform method that gives perfect distinction in time and frequency areas. The Page transform which belongs into the quadratic time-frequency distributions covariant by shift in time and in frequency, offers a wide set of powerfull tools to analyse non-stationary signals. The basic idea is to devise a joint function of time and frequency that describes the energy density or intenzity of a signal simultanneously in time and in frequency.
