Использование: изобретение относится к области измерительной техники, а именно к устройствам для определения соотношения фаз, в частности к устройствам для определения синфазности или противофазности двух синусоидальных сигналов. Цель: увеличение точности измерений при расширении функциональных возможностей. Сущность изобретения: после деления величин исследуемых сигналов друг на друга получают сигнал-частное, значение которого усредняют на интервале полупериода сигнала-делителя, а синфазность или противофазность определяют, когда текущие значения сигнала-частного не отличаются от усредненного значения сигнала-частного на величину, больше ошибки метода сравнения. Устройство содержит блок деления, блок усреднения и блок сравнения. Положительный эффект: предлагаемое устройство не только позволяет четко определять синфазность или противофазность исследуемых сигналов, но и имеет существенные преимущества перед другими устройствами по своей простоте и точности, особенно в инфранизкочастотном диапазоне даже тогда, когда амплитуды исследуемых колебаний значительно различаются между собой, изменяясь в большом динамическом диапазоне.Usage: the invention relates to the field of measurement technology, namely, devices for determining the ratio of the phases, in particular to devices for determining the in-phase or anti-phase of two sinusoidal signals. Objective: to increase the accuracy of measurements when expanding functionality. The essence of the invention: after dividing the values of the studied signals on each other, a signal-partial is obtained, the value of which is averaged over the half-period of the signal-divider, and the synphase or anti-phase determine when the current values of the private signal do not differ from the average value of the private signal by more comparison method errors. The device contains a division unit, averaging unit and comparison unit. Positive effect: the proposed device not only makes it possible to clearly determine the in-phase or anti-phase character of the signals under study, but also has significant advantages over other devices in terms of simplicity and accuracy, especially in the infra-low frequency range, even when the amplitudes of the studied oscillations vary considerably among themselves, changing in a large dynamic range.
