The article presents a study in the field of creation of a brain microcomputer controlled by means of human brain biosignals. This project is a symbiosis of microcomputer technologies and brain-computer interface and differs from existing analogues in that neurofeedback is carried out not only by external devices as in the case of the classical use of braincomputer interface, but also by a microcomputer, which is part of the brain-computer interface. This approach will create a competitive analogue of smartphones.

Problem of Fano resonance characterization in optical biosensors of the refractometric type based on ring $pi$ -shift fiber Bragg grating is raised. The use of this type biosensors makes it possible to increase the sensitivity of detecting changes in the refractive index of the medium under investigation to a level ${(1-2)mathrm{x}10^{-9}}$ RIU. The given sensitivity values are achieved due to the formation of a high-quality Fano resonance in the grating with the contour width at half-height of 1–5 pm. However, the possibility of obtaining significant gains in metrological characteristics poses the problem of characterizing such narrowband resonances, since the existing optical spectrum analyzers and interrogators do not have the appropriate resolution. To solve this problem, a microwave photonics method of three-frequency probing of an ultra-narrowband and asymmetric Fano contour with symmetric amplitude-modulated radiation and unbalanced amplitude sideband components is proposed. Previously one can use microwave photonic method of dual-frequency symmetric balanced probing with equal amplitudes of components and the suppressed carrier for solving such problem. Unlike it, using of proposed method, resolve to get unambiguous determination of the center frequency, maximum amplitude and quality of Fano contours, as well as the possibility of significantly simplifying the technique of collecting information about their parameters. It should be noted that decision has also to be true for the characterization of Fano resonance with its symmetrical realizations. This article consistently reflect the questions of posing the problem and discussion of ways for it decision.

A method of reliability assessment of a fiber optical communication line (FOCL) is proposed taking into consideration the temperature actions on optical fibers. The reliability of the FOCL is estimated by a readiness coefficient. Theoretical studies are performed using Markov chain theory and probabilistic mathematical simulation. The accepted value of the readiness coefficient allows us to determine the maximum servicing interval for FOCL. The paper was financially supported by the Ministry of Education and Science of the Russian Federation within the framework of the basic part of the state task in the field of scientific activity (project No. 8.9334.2017/8.9).

For approximation and time-frequency analysis of continuous signals, it is proposed to use non-causal complex exponential models defined in the general case on an infinite two-way time interval. It is shown that the space of such model signals is Euclidean and rigorous analytical expressions are obtained for their main characteristics in the time domain and spectral domain - convolutions of signals, cross-correlation functions, spectrum and cross-spectral densities, etc. The possibilities of applying the obtained formulas in the Matlab system are demonstrated.

In this paper results of modeling parameters of the compact double-gap resonator for 19-beam klystron type devices with a resonant fractal structure of the Greek-cross type for “0-th”, “1-st” and “2-nd” iteration are submitted. Resonance elements made on the central electrodes of a symmetrical high-Q strip line suspended on a dielectric substrate. The resonator has two fundamental modes of oscillation: in-phase and anti-phase. The main mode of the oscillations of the resonator is anti-phase. It corresponds to the X-range of frequencies, the first higher oscillation mode (in-phase) corresponds to the Ku-band. The paper presents the results of calculation: resonance frequency f, shunt impedance R/Q and Q-factor for $pmb{pi}$ and $pmb{2pi}$ modes of oscillations. The optimal parameters of the interaction process were found also.

In the modern world, image transmission, including the transmission of television and video signals, is carried out using a preliminary and restorative correction according to the law, which was caused by the use of imaging devices on cathode-ray tubes. If we take into account the presence of several video transmission channels, for example, three for color television or more for spectral systems, then even for the first case, several color models are used for signal transmission, for example, RGB or YCrCb. At the same time, on the one hand, in the R, G, and B channels, gamma correction is not optimal from the point of minimizing the number of quantization levels when visually monitoring the image, and on the other hand, it is known that these models are not equal-contrast, a change in, for example, a color tone or saturation by a certain amount will be noticeably differently depending on the choice of the initial values of the coordinates of the selected color.

There are computational and empirical approaches to analog-to-digital converter (ADC) selection in digital receiver. Simplified calculation methods are based on the idealized ADC model. These methods take into account only the quantization noise associated with the ADC bits number, sampling frequency, signal-to-noise ratio. The calculation results has estimate character. The structural constraints to the ADC parameters are determined with the receiver realization. They must be considered when ADC choosing. The study of theoretical relationships allows identifying the computational models application area limitations. The performed analysis shows wider correlation of the radio frequency channel parameters and different ADC parameters. It is possible to consider these parameters interrelation from with regard to their effect on the received signal conversion accuracy, and make a ADCs choice based on unified methodological positions.
