In the paper the practicability of using the digital signal processing in track receivers of the tone track circuits is shown. On the basis of spectral analysis results of the signal current of the tone track circuits, as well as with taking the acting st... see more

Based on the analysis of existing methods of checking the tonal frequency track circuits, the choice of parameters and options for check automation of tonal frequency track circuits is conducted.

Introduction: With the introduction of high-speed traffic there is an increased consumption of traction current by new types of rolling stock. This issue is important, as high levels of traction currents can have not only prevents, but also a dangerous im... see more

The work is devoted to further improvement of processing algorithm of checking signals of rail line. The simulation modeling of correlation track receiver of tone rail circuits has been executed; the benchmark analysis of correlation receiver and direct a... see more

In this paper, the basic principle and characteristics of a phase-locked loop (PLL) in a single phase grid-connected system are analyzed, and this paper introduces one type virtual orthogonal voltage vector method based on a third order generalized integr... see more

Eye tracking is a well-established tool that is often utilised in research. There are currently many different types of eye trackers available, but they are either expensive, or provide a relatively low sampling frequency. The eye tracker presented in thi... see more
