Description

one

The proposal relates to the field of automation and computer technology and can be used in the calculation and processing of the statistical characteristics of the experimental baseline data.

A device for recording digital information is known, comprising a series-connected switch, a voltage-code converter, a signal generating unit, a magnetic head unit and a tape drive mechanism associated with a recording speed setting unit, which consists of sequentially connected switches, a relay unit and a gearbox. variable speed.

The proposed device is characterized in that it includes a zone length counter, an AND scheme and a zone number register. The input of the zone length counter is connected to a frequency divider, one of the inputs of the AND circuit, a switch and a converter-code converter. One of the outputs of the zone length counter is connected to the second input of the AND circuit, and its second output is connected to the switch and the zone no-meter register connected to the output of the AND circuit and to the driver.

This eliminates information loss.

The scheme of the proposed device shown in the drawing. The device contains switch 1, voltage-code converter 2,

a signal shaping unit 3, a magnetic head unit. 4, a tape-forming mechanism 5, a writing speed setting unit 6, an AND 7 circuit, a zone number register 8, a zone length counter 9,

frequency divider 10, switch 11, relay unit 12 and variable speed reducer 13. The device operates as follows. A tape for recording data is placed on a tape drive mechanism 5.

A switch 11 sets the required quantization frequency on the frequency divider 10, based on the frequency of the input signals. In this case, the frequency division of the master oscillator is performed into any selected integer.

the number of times is within 1, 2, 3 ... 2, where l is the number of binary bits of the counter-frequency divider. Simultaneously with the frequency setting, the switch 11 switches the control circuits of the relay unit 12, so that

relay, which includes in the variable speed gearbox 13 the necessary speed, providing the maximum allowable recording density. Next, the device is started.

The first clock pulse coming from the frequency divider 10 connects the first channel of the switch 1 and starts the voltage-code converter 2. At the same time, the same clock pulse enters the length counter

zone 9 and the scheme "And 7. With the output of the scheme" And 7

a clock signal is supplied to the zone number register 8, from which enters the signal generation unit 3. At the same time, block 3 receives a parallel binary code from the voltage-code converter 2, the converted input signal on the first channel.

Thus, from block 3, the code of the number and the first bit of the serial binary CODE marker (zone number), which are recorded on a magnetic tape, come to the same block of magnetic heads 4. With the arrival of the second clock pulse, the second channel of the switch is selected, and the process of recording the number code and the second bit of the sequential code of the marker on the magnetic tape again occurs. This is repeated until t shifts are made in the zone number register 8, where t is the number of binary bits of the sequential marker code (zone number), and the zone number 8 register is configured as a ring, so after extending and writing the number zone remains in the zone number register. After the shifts, the AND 7 circuit is closed, and the subsequent conversion and recording of voltage-code 2 transducer codes does not extend and write markers until a subsequent zone is formed, and the transform input signals continue to be recorded on the magnetic tape.

After the end of the counting of a given number of samples in the zone length counter 9 (the volume of the zone

is selected, based on the post-processing program on the digital computer), at its first output, a signal appears that adds "one to the register of the zone number 8, thereby changing the numbering of the marker, and also resets the switch 1 to the new zone always started with the first channel.
