FIELD: electricity.
SUBSTANCE: two electrical signals are multiplied, the first of which is produced by isolation of signal of the second harmonics of periodical frequency of rectangular unipolar pulses of constant amplitude, time duration of which is definitely and linearly related to value of phase shift between harmonic single-frequency electrical signals, at the same time the second factor is functionally related to vector of electrical signal, projection of which at appropriate direction is determined.
EFFECT: improved validity of produced information on projection of the first vector of voltage onto orthogonal direction of the second vector of voltage under conditions of distortion of sinusoid forms of electrical signals.
