A mathematical model of a PLL with fractional frequency dividers using delta-sigma modulation and a frequency-phase detector with nonidentical values of charge-pump currents is obtained. On the basis of the obtained model, a program has been developed for calculating the level of interference of fragmentation.

Analytical expressions are found for determining the duration of transients during frequency tuning of synthesizers with devices that reduce the slip time. Comparison of the results of calculations using these expressions and the results of modeling of transients in a third to fifth PLL synthesizer using the SIMULINK system of mathematical calculations MATLAB has been carried out.

The implementation of the algorithm for generating pseudo-random signals formed on the basis of the modified Lorentz system over a finite Galois field in the FPGA was considered. The received signals were matched with the previously generated method of computer simulation. The possibility of implementing pseudorandom signal generators based on the Lorentz system on relatively inexpensive and simple FPGAs is shown. The results of the work can be used to build communication systems with broadband signals, in modeling and cryptography.

The article discusses a possibility of using fiber-optic sensors based on address fiber Bragg structures (AFBS) to assess a dynamic of tire. A motivation for a study is to develop an economically sound sensor system for measuring forces acting on a wheel. A description of multisensory measurements technology of continuous monitoring of the tire state was presented and disscused. Information from the sensors is used as input parameters of algorithms that allow evaluating key characteristics, such as longitudinal and lateral friction forces. One of the advantages of this new technology is the fact that an optical photodetector is used as microwave photonic interrogator, which greatly simplifies the system.

A single scheme of klystron parameter optimization is considered, which includes structure optimization and optimization of the maximum number of input parameters (all parameters of group B). This optimization had been called as the full global optimization (FGO). Discusses two methods FGO: stage-by-stage optimization for the standard configuration of the klystron and the embedding method for the klystron configuration with higher harmonics cavities. It is shown that both methods allow reaching the level of klystron efficiency up to 90%.
