Изобретение относитс к приборостроению и может быть использовано дл анализа перемещений магнитной ленты в трактах лентопрот жных механизмов аппаратов магнитной записи.The invention relates to instrumentation and can be used to analyze the movement of a magnetic tape in the paths of the tape mechanisms of magnetic recording apparatus.
Известны устройства дл анализа поперечных перемещений магнитной ленты дл анализа колебаний скорости движени , содержащие блоки магнитных головок, усилители-формирователи, временные дискриминаторы 1 - 4.Apparatus for analyzing transverse movements of a magnetic tape for analyzing fluctuations in the speed of movement, comprising blocks of magnetic heads, shaping amplifiers, temporary discriminators 1-4, are known.
Однако при помощи устройств нельз проанализировать одновременно поперечные перемещени магнитной ленты и колебани скорости ее движени , что сказьшаетс на точности анализа.However, using the devices, it is impossible to simultaneously analyze the transverse movements of the magnetic tape and the fluctuations of its speed, which affects the accuracy of the analysis.
Известно также устройство дл одновременного анализа поперечных перемещений и колебаний скорости движени магнитной ленты, содержащее магнитную головку записи, соединенную с генератором периодического сигнала, две головки воспроизведени , рабочий зазор одной из которых расположен под углом к рабочему зазору другой, усилители-формирователи, частотньш дискриминатор , частотно- импульсный демодул тор, подключенный через усилитель-формирователь к головке воспроизведени и решающее устройство 5.It is also known a device for simultaneous analysis of transverse movements and fluctuations in the speed of movement of a magnetic tape, comprising a magnetic recording head connected to a periodic signal generator, two reproduction heads, the working gap of one of which is angled to the working gap of the other, amplifiers-formers, frequency discriminator, a frequency-pulse demodulator connected via a power amplifier to the playback head and a resolver 5.
Недостатком устройства вл етс недостаточна точность измерений в результате погрещностей измерений из-за вли ни амплитудных потерь, что ограничивает динамический диапазон.The drawback of the device is the insufficient accuracy of measurements as a result of measurement errors due to the influence of amplitude losses, which limits the dynamic range.
Целью изобретени вл етс повышение точности измерений.The aim of the invention is to improve the measurement accuracy.
Достигаетс это тем, что устройство содержит коммутатор, через который двухдорожечный блок магнитных головок, выполненный универсальным, соединен с генератором периодических сигналов и усилител ми-формировател ми, две депи, через которые усилители-форл-шрователи подсоединены к решающему устройству, состо щие одна из последовательно соединенных схемы задержки и фильтра нижних частот друга из последовательно соединенных с раздельными входами и другого фильтра нижних частот, причем другой вход триггера соединен с выходом схемы задержки.This is achieved by the fact that the device contains a switch, through which the two-track block of magnetic heads, made universal, is connected to a generator of periodic signals and amplifier-formers, two depy, through which the for-shaving amplifiers are connected to the resolver, consisting of one of serially connected delay circuits and a low-pass filter of the other one connected in series with separate inputs and another low-pass filter, with another trigger input connected to the output of the rear circuit rzhki
На чертеже схематично изображено устройство ОЛЯ анализа перемещений и колебаний скорости движени магнитной ленты.The drawing schematically shows the device OLYA analysis of movements and fluctuations in the speed of movement of the magnetic tape.
Устройство содержит универсальный двухдорожечный блок 1 магнитных головок, рабочий зазор одной из которых расположен под утлом к другой. Блок через коммутатор 2 соединен с генеThe device contains a universal two-track unit 1 magnetic heads, the working gap of one of which is located under the fragile to the other. The unit through switch 2 is connected to the gene
