Description
Основное отличие способа состоит в получении сравнивающего сигнала той же величины и с той же ошибкой регулировани , что и начальный уровень, дл чего примен ют смеситель 5 и управл емый гетеродин 6. Эти сигналы вычитают с помощью дифференциального усилител 7, благодар чему при -равенстве и синфазности входных сигналов измерите.ть 8 автоматически устанавливаетс точно на нулевой отметке. Дл автоматического ноддерл ани синфазности указанных сигналов используют фазовый детектор 9 с незначительными амнлитудно-фазовыми погрещност ми. Выходным напр жением его воздействуют на управл ющий элемент гетеродина 6, благодар чему поддерживают требуемую синфазпость.The main difference of the method consists in obtaining a comparison signal of the same magnitude and with the same control error as the initial level, for which mixer 5 and the controlled local oscillator 6 are used. The input phase signals measured. 8 is automatically set to exactly zero. Phase detector 9 with minor amnlitud-phase faults is used for automatic node-phase synchronization of these signals. Its output voltage acts on the control element of the local oscillator 6, thereby supporting the desired synphase.
Предмет изобретени Subject invention
Способ измерени отношени амплитуд двух переменных сигнало;в, заключающийс в том, что два сигнала совместно усиливают, раздел ют и по одному из сигналов регулируют коэффициент усилени , отличающийс тем, что, с целью новышепи точности измерени , один из сигналов преобразуют в частоту другого, устанавливают синфазность обоих сигналов, после чего последние вычитают один из другого.A method of measuring the amplitude ratio of two variable signals; c, which consists in that the two signals together amplify, separate and, by one of the signals, adjust the gain factor, characterized in that, in order to improve measurement accuracy, one of the signals establish the common mode of both signals, after which the latter subtract one from the other.
