Description

Таким образом, на обоих входах элемента PI 8 напр жени  единичны только в том случае , если частоты входного сигнала совнадают с частотой блока 5 выделени  нулевого наир жени . На выходе элемента И 8 ио вл етс  единичный сигнал, и выходной формирователь 4 импульсов срабатывает.Thus, at both inputs of the PI 8 element, the voltages are single only if the frequencies of the input signal coincide with the frequency of the zero gain selection block 5. At the output of the element, And 8 Io is a single signal, and the output driver 4 pulses is triggered.

Поскольку блок выделени  нулевого напр жени  не  вл етс  колебательной системой, то ее инерционность ничтожно мала по сравнению с узкополосным фильтром.Since the zero voltage isolation unit is not an oscillatory system, its inertia is negligible compared to a narrowband filter.

В результате быстродействие предлагаемого приемипка возрастает более, чем на пор док по сравнению с известным ири прочих равных услови х.As a result, the performance of the proposed acceptance increases by more than an order of magnitude compared to the known other equal conditions.
