Использование: в области измерительной техники, а именно - в устройствах для определения различной в синфазности и противофазности двух гармонических колебаний одной частоты, и предназначено для преимущественного использования в прецизионных устройствах, в которых необходимо знать фазовые соотношения исследуемых сигналов. Цель: увеличение точности при расширении функциональных возможностей. Сущность изобретения: совершив деление величин исследуемых сигналов друг на друга, идентифицируют синфазность и противофазность по знаку сигнала-частного, когда модуль экстремального значения сигнала-частного на полупериоде сигнала-делителя не отличается от модуля любого другого значения сигнала-частного внутри рассматриваемого полупериода на величину, больше ошибки метода сравнения. Устройство содержит блок деления, блок выделения экстремумов, блок сравнения и компаратор. Положительный эффект: предлагаемое устройство не только позволяет четко различать синфазность и противофазность исследуемых сигналов, но и имеет существенные преимущества перед другими устройствами по своей простоте и точности, особенно в инфранизкочастотном диапазоне даже тогда, когда амплитуда исследуемых колебаний значительно различаются между собой, изменяясь в большом динамическом диапазоне.Usage: in the field of measurement technology, namely, in devices for determining two harmonic oscillations of one frequency that are different in phase and antiphase, and is intended for primary use in precision devices in which it is necessary to know the phase relationships of the signals under study. Goal: increase accuracy when extending functionality. The essence of the invention: by dividing the magnitudes of the studied signals into each other, they identify the in-phase and out-of-phase characteristics by the sign of the private signal, when the modulus of the extreme value of the private signal on the half-period of the divider signal does not differ from the module of any other private signal value within the considered half period by more comparison method error. The device comprises a division unit, an extremum extraction unit, a comparison unit and a comparator. Positive effect: the proposed device not only makes it possible to clearly distinguish the in-phase and out-of-phaseness of the signals under study, but also has significant advantages over other devices in their simplicity and accuracy, especially in the infra-low frequency range, even when the amplitude of the oscillations under study significantly differ from each other, changing in a large dynamic range.
