Изобретение относитс к устройствам контрол , преобразовани и измерени параметров электрических цепей и определ е ых ими величин.The invention relates to devices for monitoring, converting and measuring the parameters of electrical circuits and the quantities determined by them.
Известен автоматический мост, позвол ющий измер ть параметры трехэлементного двухпо.пюсника. Его работа основана на подаче коротких и длинных импульсов напр жени на содержащую исследуемый и образцовый двухполюсники мостовую цепь и последукнцем ее уравновешивании регулировкой параметров образцового двухпо .люсника 1 .The automatic bridge is known, which allows to measure the parameters of a three-element two-pole mode. His work is based on the supply of short and long voltage pulses to the bridge circuit containing the test and exemplary two-terminal and to balance it by adjusting the parameters of the exemplary two-pole link 1.
Однако подача коротких и длинных импульсов равносильна пропусканию через иссследуемый объект тока высокой частоты и посто нного тока, что не всегда допустимо, так как может вызвать необратимые изменени в объекте , например, в объектах электрохимической или биологической природы.However, the supply of short and long pulses is equivalent to passing high frequency and direct current through the test object, which is not always permissible, since it can cause irreversible changes in the object, for example, in objects of electrochemical or biological nature.
Известен также преобразователь, работа которого основана на подаче полигармонического сигнала на содержащую исследуемый и образцовый двухполюсники цепь сравнени , на формировании завис щего от параметров двухполюсников напр жени и на уравновешиваний цепи сь-авнени путемA converter is also known, whose operation is based on applying a polyharmonic signal to a comparison circuit containing a test and exemplary two-terminal circuit, on the formation of a voltage depending on the parameters of the two-terminal circuits, and on equilibrating the c-link network by
минимизации (сведени к нулю) сформированного напр жени регулировкой параметров образцового двухполюсника, Этот преобразователь параметров трехэлементных ДВУХПО.ПЮСНИКОВ в напр жение содержит генератор полигармонического сигнала, подключенный через резисторы ко входам двух операцион . ных усилителей, в обратную св зьminimization (reduction to zero) of the generated voltage by adjusting the parameters of a model two-terminal circuit. This converter of parameters of three-element TWO. PUSHES INTO VOLTAGE contains a polyharmonic signal generator connected via resistors to the inputs of two operations. feedback amplifiers
одного из которых включен исследуемый двухполюсник, а в обратную св зь другого - образцовый двухполюсник с регулируемыми элементами и с идентичной исследуемому двухполюсникуone of which includes the studied two-port, and in the other's feedback an exemplary two-terminal with adjustable elements and with the same studied two-terminal
