The correction correction unit 13 (FIG. 3) comprises a second counter 20, a delay element 21, a first shifter 22, a second shifter 23, a first inverter 24, a counter 25. Address, a third element AND 26, an element P1PJ 27, a second inductor 28, a fourth element And 29, fifth element and 30.

The device works as follows.

Before starting work, block 2 records information about the telemetric program (floor of constants 3, masks 4, and amendments 5).

Each bit field 4 of the mask corresponds to a certain initial channel number. The presence of 1 in the bits of the field 4 masks means that the corresponding source channels are to be selected and redirected. For each word, the floor of the 4 masks corresponds to a constant in which the number of channels selected and redirected from the beginning of the floor of the 4 masks is written until the next word is read.

A feature of the device is that in the field of 4 masks, lines with solid zeros are not recorded,. and information on how to find, when accessing nojm 4 masks, an excluded or moved line is recorded in field 5 of the amendments in the form of an amendment code. The amendment code is equal to the number by which the address of the selected line on the second, adder 11, must be reduced to find out its new (true) position.

The floor of the masks 4 and 5 amendments look like this

The correction code for each line is entered in field 5 of the amendments. Moreover, if the first bit (sample flag) of the correction code is 1, then this means that at least one of the channels corresponding to the given line is to be selected; if it is equal to O, then the device stops working and it proceeds to the analysis of the next channel number moment.

The maximum possible number of bits for storing the correction code (with a sample sign) for telemetry of 2 channels will be: 1 2; 2.3-3; ...; 2 -10, i.e. as the address grows, an increasing number of bits are required to write the correction code.

Since the information receiving unit 1 monotonously arrives. The increasing channel numbers, in this device, the number of bits equal to the number of binary bits is allocated to the correction code in this device to store the channel number. In this case, in the 5 amendments field of the RAM 2, the correction codes are placed sequentially. The device organizes an associative sample based on the sequential allocation of the correction codes in the allocation selection block 13.

The operation of the device begins when the first channel group number arrives at reception unit 1 after synchronization of the telemetry system, for example, over a frame pause.

The channel group number is fed to the second adder 11 and to the input of the block 12 for decoding the number of significant bits, the output of which removes and feeds the number of maximum necessary bits to the input of the allocation block 13, the number I1 "1pulses" channels.

Block 13 feeds to the second adder I1 an amendment code (in the return code) or a sign of the end of the device operation by telemetry of this channel if there is O in the discharge sign of the sample. The second adder 11 subtracts the correction code from the code of the incoming channel number and sends the result to the block 2 of the operational memory 5 ti. As a result of accessing the memory unit 2, the contents of the required word 4 in the field of masks are read from it.

Half 4 masks are fed to

0 a block 7 for allocating bits of a floor of masks of a read word. The same block of the channel number code (i.e. the channel numbers in this group

g channels), defining the number of the floor and 4 masks.

Block 7 for extracting bits of the floor of the masks of the read word includes the corresponding Q bits of the masks of the read word that go to the counter 8. It forms a binary code corresponding to the number of units in the selected part of the word. This binary code is fed to adder 9, where it is summed up with the contents of the sex of the read word.

The bits of the field of 4 masks of the word being read go to the block 6 of the control signals of the masks, to another input of which the lower bits from the block 1 receive information.

In block 7, the corresponding bit of the floor of the read word masks is allocated. If 1 is stored in the field of 4 masks, it is the control signal for the valve 10, as a result of which a new device appears on the output buses of the device

the channel number formed by the first adder 9. If, on the order of 4 fields, the masks are stored O, then nothing is output to the output. The device is silent until the next channel number information appears at the input of the unit 1 for receiving information.

Block I2 of decoding the number of significant bits works as follows.

After synchronization of the telemetry system, for example, by a personnel pause, the second adder 11 is nuzzled. the number of minimum bits required to record a given channel group number. The tracking sync pulse records the channel group number in the shift register 14 and starts the 17 clock pulse generator, which sequentially shifts the channel group number towards the higher bits until the first 1 appears and counts the number of remaining bits. The first counter 18 has as many bits as the shift register 14.

Correction allotment unit 13 (FIG. 3 works as follows.

After synchronization with a personnel pause from the floor of the 5 amendments, the first word is read into the first shifter 22 of the correction selection block 13.

By reading pulse the second counter

20back. The sync pulse of the channel (in this case, the first one) zeroed the second shifter 23.

Pulses from the output of block 12 of decoding the number of significant bits go to counter 20 and through the element

21 delays - to the first shifter 22. As a result, a census takes place from the first 22 to the second 23 shift of the line number correction, which is then inverted and fed to the second adder 11. As soon as the second counter 20 overflows

it sends a pulse to the address counter 25, in which the higher bits before the operation of the device are entered the initial address of the array of corrections (field 5 amendments) of the RAM 2

Thus, block 13 of the amendment enters the second adder

I code of the amendment or a sign of the end of the device to work on the given channel number in the absence of

sign of sampling this line.

At the second adder I get the row address of the field of 4 masks, one of the bits of which corresponds to the channel number to be processed.
