METHOD AND DEVICE FOR ESTIMATING AND INDICATING DISTORTIONS OF OUTPUT SIGNAL OF AUDIO FREQUENCY AMPLIFIERS (OVERLOAD INDICATION) Russian patent published in 2006 - IPC G01R23/20 G01R19/165 

Abstract RU 2274868 C2

FIELD: technology for estimating and indicating distortions of output signal of audio frequency amplifier, appearing as a result of its top limit in sound frequency amplifier (amplifier overload).

SUBSTANCE: statistic coefficient of output signal is measured, such as dispersion, average-quadratic value, average-rectified value, average number of exhausts. Produced estimate is compared to preset threshold value. Threshold value is determined on basis of subjective-statistical expertise, showing noticeability grade of distortions. On basis of comparison results, decision about indication of distortions is taken.

EFFECT: increased efficiency of indication of audio signal distortions due to consideration of psychic-physiological particularities of humans.
