RT Journal Article ID 63c99e6a6f90661d A1 Tupota, V. I. A1 Lyutikov, V. S. T1 The Technique for Determining Characteristics of the Noise Signal Spectrum of Facilities Used for Active Protection of Acoustic Speech Information JF Telecommunications and Radio Engineering JO TRE YR 2007 FD 2007-11-08 VO 66 IS 17 SP 1573 OP 1582 AB A technique is suggested for determining amplitude and phase characteristics of the noise signal spectrum in facilities used for active protection of acoustic speech information. Determination of these characteristics allows optimization of spectral characteristics of the signal received from facilities used for active protection of acoustic speech information and assessment of their compliance with requirements to effective protection of acoustic speech information.
