Description
1, блок 6 объединени , ггодключсшш: к блоку 7 времени, шаговому дпш-атолю 8, блоку 5 Кодировани и тактовому генератору 9, выполненному с эталонным источником Ю и распределителем 11. Устройство содержит так же анализаторы 12 Погрешности и преобразователи 13 сигналов.1, block 6 of the combination, year switched on: to block 7 of time, step DPS-8, block 5 Coding and clock generator 9, made with reference source H and distributor 11. The device also contains analyzers 12 Error and signal converters 13 signals.
Устройство снабжено сумлиторами 14 ключами 15 и узлами 16 сравнени .The device is equipped with the adders 14 with the keys 15 and the nodes 16 of the comparison.
Преобразователи 13 выполнены в виде р да полосовых фильтров 17 и амплитудных детекторов 18.The transducers 13 are made in the form of a series of bandpass filters 17 and amplitude detectors 18.
Между выходами анализаторов 12 и входами узлов 16 включены фильтры 1 нижних чистот.Between the outputs of the analyzers 12 and the inputs of the nodes 16 included filters 1 lower purity.
Устройство работает следуюшим образом .The device works as follows.
Сигнал от каждого из источников 20 раздел етс фильлграми 17 на полосы частот. Амплитудные значени полосных сигналов выдел ютс детекторами 18 и сравниваютс в узлах 16 с текущим значением напр жени , величина которого определ етс сложением в сумматоре 14 несущественных составл ющих, прошедших через ключи 15. Ключи 15 открываютс инверсными сигналами с выходов узлов 16. Существенные составл ющие через элементы 2, которые управл ютс сигналами с выходов схем И 3, Подаютс на вход блока 5 кодировани , с выхода которого кодовый сигнал через блок 6 объединени и головки 21 записываетс на носитель 22. В блок 6 объединени подаютс так же код адреса от распределител 11 и код времени от блока 7. После записи строки с блока 6 на шаговый двигатель 8 подаетс сигнал запуска.The signal from each of the sources 20 is divided by filtergrams 17 into frequency bands. The amplitude values of the bandpass signals are extracted by the detectors 18 and compared in nodes 16 with the current voltage value, the value of which is determined by adding in the adder 14 nonessential components passing through the keys 15. The keys 15 are opened by inverting signals from the outputs of the nodes 16. The essential components through elements 2, which are controlled by signals from the outputs of the And 3 circuits, are fed to the input of coding unit 5, from whose output the code signal through the combining unit 6 and the head 21 is recorded on the carrier 22. In the combining unit 6 are given the same address code from the distributor 11 and the time code of the recording unit 7. When a line unit 6 to the stepping motor 8 is supplied a start signal.
Контроль допустимой Погрешности позвол ет Повысить точность записываемых сигналов.The control of permissible Error allows to increase the accuracy of the recorded signals.
