The paper analyzes the principle of the modular approach, and in analyzing the main obuchenii.Rassmotreny printsipypy modular training behind him osnove.Pokazano that the modular training focused on the learning process of students. Training modules allows invarianteost bachelor's and master's degrees, and allows you to instantly adapt the learning process to any group of learners
The work is devoted to the protection of humans from the effects of electromagnetic radiation. Today it is necessary to formulate the basic principles of electromagnetic bezopvsnosti which basis is hygienic regulation of electromagnetic radiation and carrying out sanitary control of the sources of the izlucheniya.V formulated conditions and given the method of their implementation, taking into account the maximum permissible levels, while exposure from multiple sources EMI RF
The paper evaluated noise immunity measuring devices. For this purpose, the analysis of the mechanism of formation of the longitudinal and transverse interference. It is shown that the measurement of noise immunity increases significantly when switching to converters with symmetrical vhodom.Privodyatsya analytical expressions for ootsenki noise immunity when exposed to longitudinal and transverse interference.
The paper discusses the basic principles of network resources based on the synthesis of pedagogical experience and knowledge of experts in the field of & nbsp; information technology. The analysis of the main stages of building a network of educational resources. It is shown that large amounts of information, specific to educational multimedia courses.
Various aspects of realization of the right of the Jewish population of the Russian Empire on access to the higher education are considered by the authors. They trace interrelation of processes of expansion of access to the higher education and formations of institutions of Civil Society in Late Imperial Russia.
The suppression of the nonlinear distortions in amplifier using the effect of the envelope signal of the amplified HF oscillations on the amplifier parameters is analyzed. A slow (on the time scale of the HF oscillations) variation in the parameters gives rise to additional frequency components of oscillations that compensate for the nonlinear distortions of the original signal. Several variants to employ the compensating signal using the feedback circuits in the transistor amplifiers and variations in the electron-beam current in TWT in the absence of such circuits are considered. The suppression of the nonlinear intermodulation distortions (IMDs) of the test two_frequency signal is studied for the above variants and the suppression of the third_order IMD by 6–19 dB corresponds to the known experimental data on the microwave transistor amplifier. The generalization of the quasistationary method for the analysis of the nonlinear transformation of signals allows the analysis of the amplification and suppression of IMD for more complicated multifrequency signals that are used in radio systems.
