Способ предназначен для обеспечения высокой точности измерения сдвигов фаз при различных видах обработки сигналов с известным отношением их амплитуд, значения которых могут изменяться в широких пределах. Цель: повышение точности измерения. Сущность изобретения: производят деление величин одного отфильтрованного сигнала-делимого на величины другого отфильтрованного сигнала-делителя и получают значения сигнала-частного, определяют значение его производной в момент времени t1, когда сигнал-делитель достигает своего экстремума, а значение сдвига фаз F0 определяют по несложной формуле, причем для конечного определения сдвига фаз F0 сигнала-делимого относительно сигнала-делителя в интервале от минус П до плюс П учитывают знак производной сигнала-частного и квадрант для F0: Положительный эффект: малая погрешность измерения величин фазовых сдвигов в инфранизкочастотном диапазоне для различных соотношений значений амплитуд исследуемых сигналов, высокое быстродействие, простота реализации.The method is designed to ensure high accuracy of measurement of phase shifts in various types of signal processing with a known ratio of their amplitudes, the values of which can vary within wide limits. Objective: to improve the measurement accuracy. The essence of the invention: divide the values of one filtered signal-divisible by the values of another filtered signal-divider and get the values of the signal-private, determine the value of its derivative at time t 1 when the signal-divider reaches its extremum, and the value of the phase shift F0 is determined by simple formula, and for the final determination of the phase shift F0 signal-divisible relative to the signal-divider in the interval from minus P to plus P take into account the sign of the derivative of the signal-private and the quadrant for F0: Polo Strong effect: low measurement error of phase shift values in the infra-low-frequency range for different ratios of the amplitudes of the studied signals, high speed, ease of implementation.
