one information frame. Information frames enter the device (IRs come at a certain frequency. Next, IRs are separated by KCC signals that arrive simultaneously with the word of the first polled channel. Each word is accompanied by a TCC signal. Words and KCC and TCC signals form together the frame structure of input signals On a tape (ml), each word is recorded at a certain place, i.e. at a certain physical position of the ML. This place is considered as the number of the information channel.

After passing the pulse shaper through the shaper 1, the TCC and CS signals are rectangular pulses with an amplitude of 5 V and a duration of 50–150 MKS. The arrival period for TCC signals is typically 400-700 MKS. Since the IR can be from 60 to 200 or more channels.

one information frame. Information frames (IR) are received at the device input at a certain frequency. From each other, IRs are separated by KCC signals, which arrive simultaneously with the word of the first polled channel. Each word is accompanied by a TCC signal. Words, signals KCC and TSS form together the frame structure of the input signals. On a magnetic tape (ml), each word is written in a specific place, i.e. in a certain physical position ML. This location is regarded as the number of the information channel.

After passing the pulse shaper through the shaper 1, the TCC and KCC signals are square-wave pulses with an amplitude of 5 V and a duration of 50–150 MKS. The arrival period for TCC signals is typically 400-700 MKS. Since the IR can be from 60 to 200 or more channels.

contains the first 9, second 10 and third 11 elements NOT, element And 12, matching elements 13-17.

Pulse driver 1 comprises a group of signal driver amplifiers made according to the driver circuit amplifier circuit used in storage devices on magnetic tape (BS-9002, BS-9004).

The selector 3 is built on a decoder, a coincidence circuit, and two mechanical switches, to which the interpreted single and decimal states of counter 2 arrive. The specified channel sets the number of the channel in question.

Register 4 is executed on triggers (K155TM7 microcircuits), the C-inputs of which receive a signal from the write output of the selector 3. Signals from the outputs of the first trigger through differentiating elements are fed to the inputs of the OR element, from which the signal goes to the reset input of the counter 6.

The device works as follows.

Means of code magnetic registration (CMR) provide the formation of multi-channel measurement information in the form of parallel binary codes (words) for each information channel. The sequence of words of all channels forms

the whole IC, then the period of its arrival is 20-150 ISS. The TCC and KCC signals arrive at counter 2, where the TCC signals are recalculated in accordance with the frame size, i.e. in accordance with the KCC signal, arriving simultaneously with the TSS, marking the first data position (the first channel). In the selector 3, the states of counter 2 are deciphered and the channel number is selected using switches; the information from which is written into register 4 by means of a signal from the output of the selector 3's recording. The selected information is fed to the multiplexer 5. The signals from the outputs of the first trigger of register 4 are through differentiating elements and the OR element arrives at the reset of the counter 6. From the clock output of the pulse generator 1 to the counter 6, time (second) marks are received, recorded on the magnetic tape along the selected track with a frequency of 1 Hz. Counter 6 counts the second marks until a reset signal is received from register 4, i.e. The first bit of the code will not change its state. The remaining signals from the outputs of counter 6 are fed to the inputs of multiplexer 5 and consistently allow it to transmit all bits of the code word to the output, stored in register 4. A signal NOT 10 transmits a signal to the device output that corresponds to a time stamp of approximately 100 ms, which separates the codes of information bits coming from register 4, the duration of which is an order of magnitude longer than the duration of the timestamp signals. Element I 12 decrypts the state of counter 6, corresponding to its initial state, for which the outputs of counter 6 are inverted.

Due to the voltage dividers of block 8, depending on the code received in register 4 during the recalculation time of signals by the counter 6, three levels of voltage are formed at the output of the device (Fig. 2): level. marker, corresponding to + 5Bi voltage level 1, corresponding to + 4V voltage; level O, corresponding to a voltage of + 1V, which correspond to 1 (level 1), O (level O), the states of the input code bits and the beginning of the codeword level sequences (marker level). Fig. 2 shows a view of a code word transformed by a device, the binary 8-bit equivalent of which is code 10110011. In such a sequence of levels, the transformed code word goes, for example, to a light beam oscilloscope or a recording device (recorder).

Variations of the code word by the device are converted and recorded in each cycle of counter 6, the duration in seconds of the cycle is greater than or equal to the number of bits in the code word being converted by the device, which is determined and specified by the time in which the first bit of the code word changes. condition. It is most efficient to use the device to transform and input the progress identifiers of a real experiment, such as the current astronomical time, the code words of which are generated at a frequency of 1 Hz and recorded over the selected channels of the information frame. In this case, for example, from a 16-bit binary time code, it is possible with the device to convert only code words of 5-16 bits. The fifth digit of the time code will then be the first digit of the code word and, changing with

period of 2 s, automatically sets the cycle of operation of the counter 6, which provides reliable and implicit conversions and input for registration of information about the current time.

Thus, by selecting and entering into register 4 the information parameter necessary for converting and entering, followed by selecting all the states of the code bits and submitting them in the form of two voltage levels to the output of the device, as well as by recalculating the change in the lower bit the code word of the second time stamps and control of these states of the switch by the code word bits with the formation of the sign of the beginning of the conversion cycle and input of the marker level, increased reliability of the conversion is provided and the visibility of the information, i.e. input in the form of a sequence of levels of code words to the means of registration or display.
