Abstract
The analysis and synthesis of measuring signals used to estimate of speech information protection in technical channels of leakage in a high-level noise and significant nonuniformities of their amplitude-frequency characteristics. Identified and investigated most significant properties of harmonic and complex measurement signals in bands of equal intelligibility. The distortion of the form of autocorrelation functions of complex measurement signals received in a noise are investigated. It is proposed to use complex measurement signals with an adjustable level of effective duration. The highest accuracy of the protection rating was obtained by using complex measurement signals with a given level of effective duration a = 0,8 s with fixed duration с T = 4 s in each band of equal intelligibility.
