FIELD: electric measurement technology. ^ SUBSTANCE: device is used for evaluating presence and degree of non-linear distortions of real random signal when the signal passes sound-amplifying section. Evaluation of non-linear distortions is based upon measurement of dispersion of output-to-input signal ratio at small group time lag. Distortions can be evaluated without interrupting operation of amplifier or switching it to specific mode of operation. ^ EFFECT: improved precision of measurement; improved reliability of operation. ^ 3 cl, 1 dwg |
