Р.Stochastic resonance has been attracting the attention of both physicists and electronics specialists for the past two decades. This phenomenon occurs when the presence of both a useful signal (usually harmonic) and noise in a nonlinear system leads to an increase in the signal-to-noise ratio at the system output when the input noise level increases within certain limits. The paper considers stochastic resonance in a radio engineering system similar to a digital filter based on the Lyapunov characteristic function. The physical nature of the stochastic resonance is investigated and its existence in a radio engineering system is confirmed by modeling.Публікація Aвтoмaтичний вимiрювaч пaрaмeтрiв фотоелектричних перетворювачів(ХНУРЕ, 2025) Махонін, В.

Я.This work is devoted to the operating principle of terahertz generators and detectors. The transmitting antenna consists of two metal electrodes placed at a certain distance from each other on a semiconductor substrate. A voltage of several kilovolts is applied to the electrodes. When the gap between the electrodes is illuminated by an ultrashort laser pulse, the concentration of charge carriers in the semiconductor increases sharply. The resulting free carriers are accelerated by the field applied to the gap, resulting in a short-term current pulse, which is a source of terahertz radiation.Публікація Зв’язок алгебраїчного та топологічного виводу правила Мезона(ХНУРЕ, 2025) Гапон, Н.

Я.This work is devoted to improvement of the thermal quadrupole model for defectoscopy of 3D printing filament products. For filament defect models, traditional are multilayer models, where the defect is located inside between two layers of filament material. It is necessary to find the geometric dimensions and electrophysical parameters of the filament. The number of independent equations is less than the number of unknowns, therefore, when deriving the relations, not all the sought parameters can be uniquely separated from each other, therefore, the task of the research is to find an additional relation. To solve this problem, the equation for minimizing the sum of the residuals was applied, which is formed by determining the derivative with respect to the distance between the layers and equating it to zero.Публікація Дослідження шумів автогенераторів на лавино-пролітних діодах(ХНУРЕ, 2025) Бурчін, Ю.
