ETU “LETI”: The Best Laboratory Works Get Support from the Endowment Fund for Development of ETU “LETI”

In December 2020, ETU “LETI” held an awarding ceremony of the Best Laboratory Work Contest. The university professors, as well as representatives of the university administration and the Endowment Fund for Development of ETU “LETI,” participated in the contest. Konstantin Abbakumov, Head of the Department of Electrical Acoustics and Ultrasonic Engineering, hosted the awarding ceremony. Participants submitted eleven laboratory works for the competition.

The contest aims to motivate teachers to improve existing laboratory works and develop new ones. According to the organizers, it contributes to the development of laboratory equipment and improves the quality of education.

“This is the third time our contest has taken place. During this time, we have been able to clearly define the target audience. It is important that participants have the motivation and desire to make their project relevant and in demand. The continuity in the transfer of experience from older teachers to younger followers is also of great value. In science, cooperation and training are very important. I am also pleased with the quality of works of the participants, their desire to innovate in development.”

The winner in the Best Laboratory Layout (Installation) category is the laboratory work titled “Study of a Phased Array with Discrete Phasing,” developed by Associate Professors of the Department of Theoretical Fundamentals of Radio Engineering Svyatoslav Ballandovich, Grigory Kostikov, and Mikhail Sugak.

“Phased arrays are the heart of high-speed radar systems. They define the characteristics of modern weapon systems such as the S-400, Patriot, and several others. At the same time, companies recently began to actively use the technology in communication systems, such as Starlink. For easier learning of the information presented in lectures, we decided to create a laboratory work, devoted to the antennas of this type.”

In the Best Laboratory Work Using PC Modeling nomination, a project called “Effects of Quantization and Rounding” took the first place. Alexander Petrov, Associate Professor of the Department Theoretical Fundamentals of Radio Engineering, and Alexander Sergienko, Deputy Head of the department, authored the work.

“When implementing digital signal processing systems, we inevitably face the problem of final accuracy of number representation in computing devices. It affects the performance of the systems, and overflows and rounding errors can occur when performing calculations. A qualified specialist must take these effects into account when designing the system, so it is necessary to teach students to understand and predict it,”

Alexander Sergienko explained.

The participants of the contest received certificates. The winning laboratory works will get video versions.
