METHOD FOR DETERMINING PHASE SHIFT BETWEEN TWO SIGNALS WITH KNOWN AMPLITUDE RATIO Russian patent published in 1995 - IPC

Abstract RU 2040001 C1

FIELD: measurement technology. SUBSTANCE: values of one filtered-off signal-dividend are divided by values of other filtered-off signal-divisor and signal-quotient is obtained; value of its derivative is determined at moment t₁ when signal-divisor reaches its extremum; phase shift f_o is determined by using equation given in description of invention; for final determination of phase shift f_o between signal-dividend and signal-divisor within the range of -π to +π sign of signal-quotient derivative and quadrant for f_o are taken into account. EFFECT: improved accuracy in phase shift measurement. 1 dwg
