FIELD: electric engineering.
SUBSTANCE: device has two band filters, two detectors, two low frequency filters, two analog-digital converters and functional converter, performing division operation in simplest of possible cases. Device requires no special test signals, and, consecutively, no generators thereof. For measurements it is enough to use arbitrary voltage from input signal source. The only necessary factor is presence of frequency components in range of source signal, for which band filters of device are adjusted.
EFFECT: higher precision.
