The article describes the approach to the formation of a simulation model of information signals, which are typical for objects with different types of defects. The dispersive analysis of the signal spectrum components in the bases of the discrete Hartley transform and the discrete cosine transform is carried out. The analysis of the form of the re...

The article analyzes the current state of methods and means of monitoring air pollution in Ukraine. The issues of the formation of pollutants during the combustion of various types of fuel (gaseous, liquid, solid) in large power plants are considered. The data about the largest sources of air pollution in Ukraine are given. The main disadvantages o...

It is proposed to apply the wavelet transform to localize in time the frequency components of the information signals in this article. The wavelet transform allows to fulfil time-frequency analysis of signals, which is very important for studying the structure of a composite material from the mode composition of free oscillations. The proposed appr...

... Various methods for diagnosing EE [1,3,6,7,9,[19][20][21][22] are known and practically used. These methods are determined by the physical process, which generates a diagnostic signal, and is measured to obtain information about the technical condition of the research node. ...
... coefficients in Hartley bases and cosine functions. Similar results are characteristic in the case of the use of discrete Fourier transforms, Haar and discrete sine transforms [15,16]. The spectral alignment is performed by a signal that is obtained by averaging 500 realizations for each of the sample zones studied. ...
