Description
создает острозгольные импульсы. На выходе же пороговой схемы (диаграмма 2, в) формируетс напр жение, среднее значение которого пропорционально частоте входного сигнала. ФНЧ производит выделение среднего значени напр жени . На фиг. 2 показаны три значени напр жений, имеющих разную частоту. Из диаграмм видно, что вне зависимости от частоты поступлени импульсов с источника 1 на выходе пороговой схемы будет надежно формироватьс пр моугольный сигнал, который позволит с такой же надежностью работать всей САР АМЗ., ,creates sharp pulses. At the output of the threshold circuit (diagram 2, c), a voltage is formed whose average value is proportional to the frequency of the input signal. The low-pass filter produces an average voltage value. FIG. 2 shows three voltages having different frequencies. It can be seen from the diagrams that regardless of the pulse frequency from source 1, a square signal will reliably be generated at the output of the threshold circuit, which will allow the entire AMS SAR to work with the same reliability.
Таким образом, за счет достаточно простых средств достигаетс возможность повышени точности демодул ции сигналов в САР, что повышает достоверность записываемой и воспроизводимой информации и уменьшает веро тность в потребности ее повторной обработки, т. е. снижаютс трудозатраты . Это особенно важно при записи и воспроизведении сигналов служебной информации , которые поворно записать или невозможно, или трудно.Thus, due to rather simple means, the possibility of increasing the accuracy of signal demodulation in SAR is achieved, which increases the reliability of the recorded and reproducible information and reduces the likelihood of the need for its reprocessing, i.e., labor costs are reduced. This is especially important when recording and reproducing service information signals, which are impossible to record, or impossible, or difficult to record.
