Частотно-часовий аналіз вібросигналів з використанням вейвлет-перетворень

Abstract

In the work the frequency-temporary technology diagnostics of vibration of machines is considered. Use for it of the mathematical device of wavelet-transformations is offered and its advantages are analyzed. The example of discrete wavelet-transformations of an any non-stationary signal and one from possible algorithms of its application is resulted.
