Currently, we are witnessing the active introduction of modern digital technologies in the field of education. One of the main reasons for this was the transition to distance learning due to the global COVID-19 pandemic. More and more virtual labs, virtual textbooks, as well as educational platforms that allow students to acquire the necessary skills and abilities remotely using the Internet, are being used in the educational process. The most promising educational platform is an interactive mobile learning platform. It has several advantages, among which one can especially single out the convenience of learning due to its interactivity and organization of the studied material. The application of augmented and virtual reality allows for increasing the effectiveness of classes. These technologies provide another level of interaction and material perception by students. However, VR and its high level of immersion require special equipment and more actions from the user while AR is cheaper and more affordable, but still interactive and has great visual aids. The aim of the paper is to demonstrate how augmented reality can be used for radio engineering disciplines on the example of an interactive mobile platform. This article discusses the process of developing a mobile platform that allows studying the material of radio engineering courses using augmented reality technology. The work also contains the results of a survey conducted among the students who used it as a part of their class activities. In addition, sections of the article contain a description of the project development process, its structure, international experience, and the conclusions.

The worldwide COVID-19 pandemic has changed the development plans of every country. Instead, governments had to constantly deal with ever-emerging issues in healthcare, education, economics and industry. As a result, there has been an accelerated introduction of digitalization in these spheres. Thus, an increasing number of people have started using electronic services that have improved their digital literacy. This feature has had a positive impact on society and helped to create new interaction tools between populations and governments, students and institutions, customers and companies. The article aims to analyze how studying radio electronics can be improved by involving new tools and how they can be applied in distance learning. This work presents the results of the development and application of a virtual radio signal simulation in the educational process in the form of a laboratory practicum. Working on this approach required specific research in the field; the foreign experience was observed and studied. The review allowed us to find out how digitalization and the application of digital tools affect the behaviour, cognition, and overall performance of students during the pandemic. The authors conducted a questionnaire among students to evaluate the features of the virtual laboratory work and their effect on the educational process. The results analyzed are given in the article. They showed that students highly appreciate the introduction of such tools in learning. Moreover, like the entire laboratory, the proposed model can be used in the educational process offline and with distance learning. Finally, the article describes the experience and results of the software package’s development and integration for the spectrum analyzer’s computer model and virtual laboratory work using the MS VS environment in C ++. The results of the conducted work demonstrate the versatility of the proposed approach, its positive impact on the educational process, high potential in the other spheres.

“…Therefore, promising in this direction is the development of inexpensive portable sensors with integrated computational cores, based on new algorithms for information transformations of the FID signal in the transmit and receive path and the visualization of NQR spectra [ 13 , 14 , 15 ]. At the same time, considerable attention should be paid to increasing the signal-to-noise ratio value provided by the sensor to the required level for error-free detection of the NQR signal in the investigated substances of small volumes with masses from tenths to several grams, and to the development of highly efficient methods for the formation of special multi-pulse sequences of nanosecond time intervals for the stochastic NQR technique [ 16 , 17 , 18 ].…”

This paper presents a method for implementing the configuration structure of an integrated computational core of a pulsed nuclear quadrupole resonance (NQR) sensor based on a field-programmable gate array (FPGA), which comprises the following modules: a three-channel direct digital synthesizer (DDS), a pulse sequence shaper and a software-defined radio. Experimental studies carried out using the in-circuit analyzer SignalTap Logic Analyzer have confirmed the reliability of the correct and stable operation of the functional modules of the configuration structure at all stages of signal transformations, starting from the formation of the envelope of the excitation pulses and ending with the obtainment of low-frequency quadrature signals at the outlet of the compensating filters. The time and frequency dependences of the amplitude of the output signals generated using the DDS based on a 48 bit phase accumulator are investigated. This development can be used when creating pulsed coherent NQR sensors in the frequency range of 1 MHz–50 MHz.
