METHOD FOR MEASUREMENT OF DIRECT COMPONENT OF SIGNAL Russian patent published in 2004 - IPC

FIELD: electroradio measurements.

SUBSTANCE: the method consists in integration and conditioning of signal . Additionally integrated are the product of the measured signal and the cosine component of the reference signal obtaining signal , the product of the measured signal and the cosine component of the n-th harmonic of the reference signal obtaining signal , cosine component and the square of the cosine component of the reference signal obtaining signals and respectively, the cosine component of the n-th harmonic and the square of the cosine component of the n-th harmonic of the reference signal, obtaining signals and the product of the cosine component of the reference signal and the cosine component of the n-th harmonic of the reference signal obtaining signal . The value of the signal direct component is computed according to the results of integration of eight signals .

EFFECT: provided measurement of the signal direct component at any time of measurement at priority unknown amplitude and phase shift both of the first and the n-th harmonics of the measured signal.
