摘要

A method of producing an analog electrical orthogonal component module signal vector of one of two single-frequency harmonic electric signals u1 (t) and u2 (t), which consists in obtaining the electric signal in the form of a periodic sequence of unipolar rectangular pulses of constant amplitude, the pulse duration is unambiguously related to the magnitude of the phase shift between the electrical signals u1 (t) and u2 (t), characterized in that the sequence of unipolar rectangular pulses of constant and amplitudes of isolated electrical signal second harmonic, the amplitude of which contains unique information about the value of the trigonometric function of the sine of the phase angle φ1 between electrical signals u1 (t) and u2 (t), and from an electrical signal of the second harmonic is formed an electric signal of the first multiplier, the electric signal of the second multiplier is formed from one of two single-frequency harmonic electric signals u1 (t) and u2 (t) and linearly connected with it, wherein the vector of the harmonic signal from which not ormiruyut second factor defines orthogonal him direction, wherein both the first and second factors can not be harmonic signals, multiply the received electrical signals factors to obtain analog electrical signal containing information about the orthogonal component of the unit vector of the harmonic signal from which was formed by the second factor.
