FIELD: measurement technology; measuring RMS value of content of higher harmonic components in signal. SUBSTANCE: analyzed signal is compared with reference sine-wave signal at fundamental harmonic frequency; ratio moduli of instant values of input and reference signals are determined at time instants t1 and t2, respectively, each equally spaced from center of selected half-wave interval of own signal; RMS value of harmonic components is determined by RMS value of product of reference of sine-wave signal by square root of difference in squares of two values: current values of radio moduli of instant values of signals and averaged value of these moduli. EFFECT: improved measurement accuracy at intraflow frequencies due to dispensing with signal filtering, this affording high speed in measuring RMS value of harmonic components; enlarged functional capabilities. 2 dwg
