Устройство используется для прецизионных измерений фазовых сдвигов между двумя гармоническими сигналами, отношение амплитуд которых равно К. Цель изобретения: увеличение точности измерения при упрощении конструкции. Сущность изобретения: устройство создано на основе способа, в соответствии с которым величины одного сигнала-делимого делят на величины другого сигнала-делителя, дифференцируют значение сигнала-частного и в момент времени t1, соответствующий середине полуволны сигнала-делителя, определяют сдвиг фаз Fo сигналов по следующему математическому выражению: Fo = -arcsin[f′(t1)/K]. Устройство содержит блок деления, формирователь управляющих импульсов, блок дифференцирования, тригонометрический преобразователь и блок выборки-хранения. Положительный эффект: устройство имеет простую конструкцию, высокое быстродействие, обладает малой погрешностью за счет измерения всего лишь единственного мгновенного значения сигнала-частного; высокая точность сохраняется и на инфранизких частотах.The device is used for precision measurements of phase shifts between two harmonic signals, the ratio of the amplitudes of which is K. The purpose of the invention: to increase the measurement accuracy while simplifying the design. The inventive device is based on the method in which the values of one signal-divisible divide by the values of another signal-divider, differentiate the value of the signal-private and at time t1, corresponding to the middle of the half-wave signal-divider, determine the phase shift The following mathematical expression: Fo = -arcsin [f ′ (t1) / K]. The device comprises a division unit, a control pulse former, a differentiation unit, a trigonometric transducer, and a sample-storage unit. Positive effect: the device has a simple design, high speed, has a small error due to the measurement of only a single instantaneous signal-private value; high accuracy is maintained at infra-low frequencies.
