Horev A.A., Bykov A.I., Sokolov A.N. «Design and research of characteristics of the analog acoustic noise generator» Вестник УрФО. Безопасность в информационной сфере, № 2, с. 4-10 (2016)

In operation is offered the diagram of the analog noise generator of system of vibroacoustic masking designed by means of a software of simulation of the electronic circuits NI Multisim and a technique of research of its main characteristics. Described requirementsfor noise generators of vibro-acoustic security systems. Formulated main tasks in the simulation of vibro-acoustic security device. Presented block diagram of an analog noise generator, concepts of its elements, oscillograms and spectra of signals at control points. Researched interfering features of noise signal and the degree of its approximation to the ideal “white” noise. It is shown that the designed noise generator fully meets the requirements, and the obtained results can be used in laboratory works on the course “Technical protection of information”.
