Evaluation of optoelectronic channel leak speech with the use of mathematical models

Abstract

In this article we analyzed optoelectronic channel leakage of voice information. It’s a method for processing the measurement signal, including an assessment of the cumulative effect of amplitude and phase modulation. Acoustic vibrations of the solid medium, subject to amplitude and phase modulation, presents a model of a rectangular vibrating membrane. The method of estimating the signal/noise ratio by using the mathematical model developed security assessment. During the research density distribution phase at various energy indicators was built showing the degree of dependence of the phase of the resulting fluctuations of the original signal.
