Изобретение относитс  к области нзморительной техники.The invention relates to the field of foreign technology.

Известно устройство дл  измерени  1колеба.иий скорости движени  матнит ной ленты, содержащее импульсный генератор, подключенный к записывающей головке с двум  |рабоч .ими зазорами, и воопроизвод щую головку, подключенную к лервому формирователю импульсов , соединенному с преобразователем временных интервалов в напр жение 1.A device for measuring the oscillation speed of a matte tape, containing a pulse generator connected to a recording head with two working gaps, and a power supply head connected to a left pulse shaper connected to a time converter into voltage 1, is known.

В известном устройстве колебани  скорости движени  ма1гнит1ной ленты определ ютс  за счет записи «а ней отдельных пар эквидистантных .маГнитных отпечатков и измерени  временных интервалов между моментами их в осп р оизведен и .In the known device, the oscillations of the speed of movement of the magnetic tape are determined by recording separate pairs of equidistant magnetic Samples of the imprint therein and measuring the time intervals between their instances in the process of producing and.

Известно та-кже устройство дл  измерени  колебаний скорости движени  -магнитной , которое содержит первый и второй фильтры нижних частот, св занные с первым и вторым индИКаторами и со входамл блока вычитани , подключенного к третьему индикатору , и преобразователь напр жени , подсоедичемный к ВЫХОДУ Т1рипгера со счетным входомAlso known is a device for measuring fluctuations in the speed of movement-magnetic, which contains the first and second low-pass filters associated with the first and second indicators and inputs of a subtraction unit connected to the third indicator, and a voltage converter connected to the T1 Trigger OUTPUT from counting input

2.2

Это устройство позвол ет производить как измерение суммы колебаний, возникающих при.записи и воопроизведении, так и изм ерение колебаний только при записи и только при воспроизведении. Однако псьдобное устройство не обеспечивает достаточно высОКую точность результата измерени .This device allows both measuring the sum of the oscillations that occur during recording and playback, and measuring the oscillations only during recording and only during playback. However, the test device does not provide sufficiently high accuracy of the measurement result.

С целью уменьшени  погрешности измерени  в предлагаемое устройство введены шнротноимпульоный демодул тор, подсоединенный к выходу триггера и к первому фильтру нижних частот, соединенные последовательно амплитудный ограничитель и одновибратор, включенные преобразователем напр жени  и вторым фильтром нилШИх частот, и соединенные последовательно схема ЗАПРЕТ, второй формирователь лмпульсов и с.хема И, подключенна  к первому формирователю и мпульсов и к счетному входу триггера.In order to reduce the measurement error, an impulse demodulator connected to the output of the trigger and to the first low-pass filter, an amplitude limiter connected in series and a single-vibration device connected to a voltage converter and a second low-frequency filter, and connected in series with a pulse converter, are connected to the device. and a schema of AND, connected to the first driver and mpuls and to the counting input of the trigger.

На чертеже изображен один из возможных вариантов предлагаемого устройства дл  измерени  колебаний скорости магнитной ленты.The drawing shows one of the possible variants of the proposed device for measuring speed fluctuations of a magnetic tape.

Предлагаемое устройство содержит нмпульсный генератор 1, подключенный к записывающей головке 2 с двум  рабочими зазорами , сопр женной с движущейс  магнитной лентой 3, последн   сопр жена также с воспроизвод щей головкой 4, соединенной черезThe proposed device contains an impulse generator 1 connected to a recording head 2 with two working gaps, coupled with a moving magnetic tape 3, the latter also connected with a reproducing head 4 connected through

первый формирователь 5 импульсов с одниМ из входов схемы И 6, подключенной к счетному входу 7 триггера 8. Выход 9 триггера 8 св зан через широтноимпульсный демодул тор 10 с первым фильтром И нижних частот,the first driver 5 pulses with one of the inputs of the circuit AND 6 connected to the counting input 7 of the trigger 8. The output 9 of the trigger 8 is connected through the pulse width demodulator 10 with the first filter And the lower frequencies
