FIELD: electronic engineering. ^ SUBSTANCE: device consists of supporting voltage generator, two square-wave generators, three multiplexers, eight integrators, control block, computing block and indicator. Signals are received by computing block, formed by first five integrators. Utilized additionally are results of integration of orthogonal components of supporting signal and result of integration of signal being measured during time of measurement. These signals are formed by sixth, seventh and eighth integrators, respectively. ^ EFFECT: realization of current continuous measuring of amplitude of harmonic signal with measuring time not mess and not divisible by period of harmonic signal without systematic error for a priori unknown constant component and phase shift of signal being measured. ^ 4 dwg |
