FIELD: electric and radio measurement technology. SUBSTANCE: procedure measuring constant component of harmonic signal is based on integration of measured signal and on formation of signal ρ, on formation of time interval symmetric relative to extremum of cosine component of reference signal and not coupled in duration to period of harmonic component of measured signal in which measured signal is additionally multiplied with cosine component of reference signal and integrated to form signal beta. Cosine component of reference signal is raised to the square and integrated forming signal beta*, then cosine component of reference signal is integrated to form signal ν*=. Later value of constant component of harmonic signal is computed by given formula EFFECT: raised measurement accuracy. 1 dwg
