Threshold signals in angle modulation

Radio engineering. Electronics


Bolshov O. A.


The article considers the issue of evaluation of degree of the information security which the engineering systems that establish leakage channels owning to the side and casual electromagnetic radiation from vocoders, are operating with, and defines the threshold levels (with minimum power) of signals for technical channels of voice data interception in angle modulation.


Threshold signals; signals of analog devices and telecommunications systems.
