Description
С возможностью взаимной синхронизации с .блоком цифровой синхронизации и временной задержки другого .формиовател сигнала,With the possibility of mutual synchronization with a digital synchronization block and a time delay of another signal former,
На чертеже показано предлагаемое стройство дл измерени фазовой хаактеристики канала магнитной записивоспроизведени .The drawing shows the proposed device for measuring the phase harakteristiki channel magnetic recording.
Устройство содержит генератор 1 измерительных сигналов и генератор 2 синхросигнала, подключенные ко вхоам сумматора напр жений 3. Выход умматора 3 соединен через преобразователь 4 со входной шиной 5 первого формировател сигнала 6, подклюенного к первому входу индикатора азовой характеристики 7. При этом преобразователь 4 выполнен в виде имитатора процесса магнитной записивоспроизведени . Выход сумматора напр жений 3 соединен также через зел магнитной записи-воспроизведени 8 со входной, шиной 5 второго формировател сигнала 6.The device contains a measuring signal generator 1 and a synchronization signal generator 2 connected to inputs of a voltage adder 3. The output of the adder 3 is connected via converter 4 to the input bus 5 of the first signal conditioner 6 connected to the first input of the indicator of the characteristic 7. At that, converter 4 is made imitator of the magnetic replay process. The output of the voltage adder 3 is also connected via the green of the magnetic recording-reproduction 8 to the input bus 5 of the second driver 6.
Каждый формирователь сигнала 6 состоит из первого и второго фильтров 9 и 10 и блока 11 цифровой синхронизации и временной задержки. При этом в каждом формирователе сигнала б фильтр 9 и 10 включены между его входной шиной 5 и входами блока цифровой синхронизации и временной задержки 11, соединенного с возможностью взаимной синхронизации с блоком 11 другого формировател сигнала б,Each signal conditioner 6 consists of the first and second filters 9 and 10 and the digital synchronization unit 11 and the time delay. At the same time, in each signal conditioner b, a filter 9 and 10 are connected between its input bus 5 and the inputs of the digital synchronization unit and the time delay 11, which is mutually synchronized with the unit 11 of another signal conditioner b,
В предлагаемом устройстве результат сложени измерительных сигналов и синхросигнала поступает с выхода сумматора 3 на узел магнитной записивоспроизведени 8 и на преобразователь .4, В первом и втором формировател х сигнала б фильтры 9 и 10 производ т разделение измерительных сигналов и синхросигнала. При этом временна задержка блока 11 в первом формирователе сигнала 6 больше временной задержки блока и во втором формирователе сигнала б на величину, определ емую временной задержкой, вносимой блоком 8,In the proposed device, the result of combining the measurement signals and the sync signal comes from the output of the adder 3 to the magnetic recording reproducing unit 8 and to the transducer .4, In the first and second signal conditioner b, filters 9 and 10 separate the measuring signals and the sync signal. In this case, the time delay of block 11 in the first signal conditioner 6 is greater than the time delay of the block and in the second signal conditioner b by an amount determined by the time delay introduced by block 8,
Использование изобретени в значительной степени уменьшает погрешность измерени фазовой характеристики канала магнитной записи-воспроизведени без усложнени конструкции устройства дл измерени фазовой характеристики канала магнитной записи-воспроизведени .The use of the invention significantly reduces the measurement error of the phase response of the magnetic recording-reproduction channel without complicating the design of the device for measuring the phase response of the magnetic recording-reproduction channel.
