Development of tunable band noise genera-tors

The aim of the work is to develop and study the principle of operation of tunable band noise generators (TBNG) and their characteristics, a noise signal conditioner of a modular type, which provides controlling the bandwidth of a noise signal for using it as a means set-ting radio noise. It is possible to do it through the formation and radiation in the surrounding space of electromagnetic fields of the energy spectrum in specified frequency ranges, with the possibility of changing the amplitude and bandwidth of the signal. To improve performance and make them more widely used in order to provide high-quality counteraction to unauthor-ized removal (by intruders) of information on emission channels of spurious electromagnetic radiation (SER), it is necessary to create multichannel adaptive TBNGs. In the developed generators in each noisy channel, it is possible to provide power adjustment, generated noise signal and noise bandwidth control, which will improve the electromagnetic compatibility of such devices. To ensure this, it is proposed to use a design concept based on the use of con-trolled modules of noise sources with band-pass filters, which also allows you to get a noise signal uniform in amplitude.
