Таким образом, измерение коэффициента усилени (пли частотной характеристики)) операционного усилител сводитс к измерению напр жени Ос в суммирующей точке и вычислению отношени напр жений L(() UK IU.-.Thus, measuring the gain (or frequency response) of the operational amplifier is reduced to measuring the voltage Oc at the summing point and calculating the ratio of the voltages L (() UK IU.-.
СГ ;у1Соидалыюе напр жение, снимаемое с сум..Енрующей точки, преобразуетс в синхронном детсЕ торе 3 в иосто нное напр жение, равное ио ампл1нтуде синусоидальному напр жению L., которое индуцируетс а1ндикатором 4.СГ; у1Содалиюе voltage, taken from the sum of the leading point, is converted in synchronous detonator 3 into a static voltage, equal to its amplitude sinusoidal voltage L., which is induced by indicator 1.
