METHOD OF MEASURING PHASE SHIFT OF TWO SINUSOIDAL SIGNALS Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: signal values X(t) are divided by signal values Y(t). At time moment t₁ when signal-divisor achieves its maximal value Y(t), values of signal-quotient f(t₁) are determined as well as value of its derivative f′(t₁). After that phase shift value F_o of signal-dividend X(t) is defined relatively signal-divisor Y(t) from the relation given in the description of the invention. EFFECT: improved precision of measurement. 1 dwg
