FIELD: electric radio measurement technology.
SUBSTANCE: device is used for estimation of presence and degree of distortions arisen in sound-amplifying section when determined monoharmonic as well as real random signal passes the section. Calculator division unit, ac/dc voltage converter and lower frequency filter which has output being output of calculator. Inputs of division unit have to test input of calculator. Output of division unit is ac connected with input of ac/dc voltage converter. Output of the converter is connected with input of lower frequency filter. Calculator is able of revealing and estimating non-linear distortions during operation without interruption and getting into special measuring mode. One more version of calculator has additional band-pass filter.
EFFECT: ability of revealing and estimating of non-linear distortions.
