Использование: изобретение относится к измерительной технике, а именно к способам определения соотношения фаз, в частности к способам определения квадратурных фазовых сдвигов двух синусоидальных сигналов. Цель: расширение функциональной возможности при измерениях. Сущность изобретения: после деления величин исследуемых сигналов друг на друга получают сигнал-частное, значение которого ограничивают и усредняют на выбранном интервале времени, а квадратурный фазовый сдвиг между сигналами определяют, когда усредненное значение будет равно нулю. Положительный эффект: предлагаемый способ позволяет с высокой точностью определять квадратурный фазовый сдвиг между исследуемыми сигналами, амплитуды которых изменяются в большом динамическом диапазоне, даже на инфранизких частотах.2 ил.Usage: the invention relates to a measurement technique, and in particular to methods for determining the phase ratio, in particular to methods for determining quadrature phase shifts of two sinusoidal signals. Purpose: expansion of functionality when measuring. The essence of the invention: after dividing the values of the studied signals on each other receive a signal-partial, the value of which is limited and averaged over the selected time interval, and the quadrature phase shift between the signals determine when the average value will be zero. Positive effect: the proposed method allows determining with high accuracy the quadrature phase shift between the studied signals, whose amplitudes vary in a large dynamic range, even at infra-low frequencies. 2 Il.
