Consider the operation of the device for inputting information on the example of the formation of a 32-bit (K 32) sequential code for an array of information consisting of 16 words (n 16).

The pulses from the output of the generator 1 pulses arrive at the counter 2, from the outputs 13-

16 of which periodic sequences of pulses with a period of 7, 27, 47, 367 are received at the inputs of synchronizer 3. The cycle of operation of counter 2 repeats itself through (4) 7 367 periods 7. In each cycle, synchronizer 3 generates an output

17pulse shift of the first register 4 (plot 44), output 18 impulse 27 (plot 48), output 19 impulse shift of the second register 8 (plot 54), pulse 47 at the output of trigger 26 (plot 41).

The shift pulses from the output 17 are fed to the input of the register 4, the outputs of which produce a sequence of clock pulses TI-j, ... TIs (charts 45-47). During the lifetime of one TI, an Okhtno device is generated and output to output 23 of the device.

32-bit word. The clock pulses of TI are fed to the p inputs of block 5, the gate input of which in each cycle from the output 18 of synchronizer 3 receives a pulse 27, the outputs of block 5 generate n pulse polling (graphs 49-51) UOi which sequentially interrogate each of the sets of switching elements of the block b. In our example of polling pulses 16. Each

0 polling pulse simultaneously polls K. bits of one word of the array dialed by the operator on block 6 of switching elements and through block 7 of the elements OR OR units are written into those bits

5 registers 8, which correspond to the unit states of the elements of block 6 in the interrogated word. After writing to the register 8 of the first word typed on the first row of block 6, the shift register 8 from the output 19 of the synchronizer 3 enters the input of register 8 (chart 54), and the output of the first register bit 8 (output 20) a sequence of pulses corresponding to the 32-bit code dialed on block 6. Simultaneously with the polling unit 6

5 switching elements, the polling pulses arrive at the inputs of the word number switch 10, where the operator selects from the sixteen polling pulses one monitored, the input to the recording register 21 of the display 11 and the rear

0 front rewrites the code word from register 8 to register 11.

Sequential codes of words from the output of the register 8 are received at the input 20 to the elements And 33-36 of the switch 9 subscribers, the inputs 22 of which receive clock

 TI pulses from register 4 outputs. On switch 9, the operator reallocates clock pulses using switches 37–39 to the R inputs of triggers 29–31 of the switch of 9 subscribers. According to the selected number of clock pulses for each subscriber, a certain number of words arrive at the outputs 23.

So, the device operates in a cyclic mode and provides asynchronous input of information to several subscribers.

The use of the essential features of the invention makes it possible to achieve a simplification of the device in comparison with the known.
