Description
Известные автоматические дешифрующие устройства, предназначенные дл обработки данных, записанных на магнитных лентах способом широтно-импульсной модул ции, весьма сложны, так как содержат многочисленную специальную аппаратуру, требующуюс дл компенсации погрещностей, возникающих от неравномерности прот жки и вибрации ленты.The known automatic decryption devices for processing data recorded on magnetic tapes by the pulse-width modulation method are very complex, since they contain numerous special equipment, which is required to compensate for the gaps caused by the unevenness of the tape and the vibration of the tape.
Описываемый способ уменьшени погрешнсюти при считывании информации , записанной а магнитной ленте способом широтно-импульсной модул ции, позвол ет сократить количество аппаратуры, примен емой в известных устройствах. Уменьшение погрешностей и сокращение количества аппаратуры, уменьшающей вли ние неравномерности прот жки и вибрации магнитной ленты, достигаетс согласно способу путем предварительной записи на ленте значени полной шкалы измерени и сравнени измер емой величины с записанным значением шкалы.The described method of reducing the error in reading information recorded on a magnetic tape by the pulse-width modulation method reduces the amount of equipment used in known devices. Reducing the errors and reducing the amount of equipment that reduces the effect of unevenness of the stretching and vibration of the magnetic tape is achieved according to the method by pre-recording on the tape the value of the full scale of measurement and comparing the measured value with the recorded scale value.
Предмет изобретени Subject invention
Способ уменьшени погрешности при считывании информации, записанной на магнитной ленте способом широтно-импульсной модул ции, отличающийс тем, что, с целью сокращени количества аппаратуры , уменьшающей погрешность при записи информации, до записи измер емой величины на ленте записывают значение полной шкалы измерени и измер емую величину сравнивают с записанным значением шкалы.A method of reducing the error in reading information recorded on a magnetic tape using the pulse-width modulation method, characterized in that, in order to reduce the amount of equipment that reduces the error in recording information, before recording the measured value on the tape, the value of the measured measurement scale and the measured value are recorded the value is compared with the recorded value of the scale.
