Description

The input bus 1 is connected to the single inputs of the flip-flops 10 and 11 and provides them with resetting to the initial state. The signal on the bus arrives with a tact of TI before starting work.

Tires 2 and 3 are connected to elements 15 and 16, respectively, and provide a constant supply of clock signals with ticks Tg and Tz to their inputs. Tires 4-8 are connected to the inputs of the decoder 19 and the key 20 and provide “wah io; oh, at their inputs to: the MGC-2 code with beat 1. Bus 9 is connected to block 21 and provides the trigger signal with beat 7i receipt of combinations of code MTK-2 to the inputs of the converter. Triggers 10, 11, and 12 are only used when running on three registers. On triggers 10 and I, the sequence of arrival of combinations of Latin letters after the digital or Russian registers is indicated. The single outputs of the flip-flops are connected respectively to the inputs of elements 13 and 14, and zero to the inputs of the element 15. Trigger 12 ensures the setting of the Triggers 10 ai 11 to the Home state. The single output of trigger 12 is connected to the input of the element 16. Elements 13-18 form control the signals for the flip-flops 10, 11 and 12 and the device 21. The outputs of the elements 13 and 14 are connected to the zero input of the trigger 12 by the block 21. The output of the element 15 is connected to the single input of the trigger 12. The output of the element 16 is connected to the single inputs of the flip-flops 10 and 11 Outputs of elements 17 and 18 Inen, respectively, with zero inputs triggers 10 and 11. The descriptor 19 provides for the formation of signals at outputs 30, 31 and 32 connected to the inputs of the switch 33, when entering its inputs, respectively, combinations of letters of Russian, Latin and numbers. Key 20 provides for the formation of tires 23-27 and 23--28, respectively, but combinations of MTK-2 code and six-element code combinations. On SNS 22, a data tracking signal is generated. Trigger 29 depletes the generation and snoring of register signals. A single trigger output 29 is connected to element 17, zero to element, volume 18 and key 20.

The switch 33 provides for the operation of the code converter (in the MTK-2 code the switch is turned off) and registerless codes in Russian and digital registers, in Latin and digital registers, in Russian, Latin and digital registers.

When working in Russian (Latin) and digital registers, the outputs 30 (31) and 32 of the decoder 19 through the switch 33 connect the tires 34 (35) and 36 with the block 21 and the tires 37 (38) and 39 respectively with the single and zero trigger inputs 29.

When operating on three rsistors through the switch 33, a number of connections are made. Exit 30 is connected by bus 34 to block 21 polls. Output 31 is connected to Shnna 42 with elsme} gms

17 and 18. Output 32 is connected to trigger 29, bus 40 s - single trigger input 10 and element 14, bus 36 - with block 21, bus 39 - with zero trigger input 29, bus 41 - with single trigger input 11 and element 13 .

The code converter works as follows.

The bus 1 receives the signal for setting the triggers 10 and 11 to the initial state. The signals from the outputs, triggers 10, and arrive at the inputs of the elements 13, 14 and 15. On the bus 2 and the third input of the element 15 with the beat T- constantly sets the sync signal. This signal, through element 15, is fed to the input of trigger 12 and sets it to its initial state. The signal from the output and the trigger 12 and the input to the element 16, to the other input of which with a clock / 3 through the bus 3 receives a clock signal. In this case, the output of element 16 did not occur; ;; 11g FO |) world signals.

The kimbination of the MTK-2 code (except for the register ones), using spies 4-8, is fed to the inputs of the desatristor 19I of the key 20.

The start-up segpal on bus 9 goes to block 21, at the output of which a signal is generated, arriving: -: i; a key 20 and bus 22. This signal opens key 20, and on buses 23-27 a combination is formed that goes to tires 4- 8, and on the bus 28 a sigial of the register register is generated, and the output from trigger 29 is formed.

With post-node: m or on tires, 4-8 combinations of letters of Russian (Latin) signal from output 30 (31) of decoder 19 through switch 33 through miine 34 (35) goes to unit 2 and prohibits its operation. At the same time, this signal via bus 37 (38) is fed to the input of trigger 29 and sets at its output potential corresponding to the sign of the Russian (Latin) registra. After that, the device works as described above. When a combination of digits arrives at output 32 of decoder 19, a signal is generated, which through switch 33 enters bus 36 to block 21, prohibits its operation, and through bus 39 enters zigger 29, installs a sweat on its output ;; .cial, corresponding to the sign of the digital-Q register, etc.

When working on three registers, if the combination of Russian letters (digits) to the inputs of the decoder 19 and the key 20, the signal from the output 30 (32) of the Cryptograph 19 through the switch 33 and the bus 34 (36) goes to the input of the block 21, terminating its operation , bus 37 (39) -a trigger input 29, set at its output a sign corresponding to the Russian (digital) register, bus 40 (41) - to the trigger outputs 10 (11), set it to its original state, and 14 (13), prohibiting the formation of a signal at its output.

If, after working on the digital (Russian) register of the bus 4-8, a combination of Latin letters arrives, this combination is formed on tires 23-27 with a sign of the digital (Russian) register. At the same time, the signal from the output 31 of the decoder 19 through the compressor 33 via bus 42 is fed to the inputs of elements 17 and 18, to the other inputs of which correspond to the single and zero outputs of the trigger 29 post} give signals. At the output of element 17 (18), a signal is generated that changes the state of the trigger 10 (11). On trigger 10 (11), information is stored that, after the digital (Russian) register, the device worked in Latin reglst150. The signal from the output of the trigger 10 (I) is fed to the inputs e; 1ment 13 (14) and 15, after 4ijjo at the output of element 15, the signal stops ;; |; l:; 1 01 ;; д11:; с,. ia.chop. Islts has eaten digital (Russian) li. from the output 32 (30) of the decoder 19 through the switch 33 through the spindle 41 (40) enters the trigger input AND (10), sets it to its initial state, and element 13 (14) .At the same time, at the output of element 13 (14) a signal that changes the state of flip-flop 12 and allows the formation of a signal at the output of block 21. Then, on tires 23 -28 a combination of numerals (letters of Russians) with the sign of a digital register is formed, and at the output of element 16 a signal is formed that sets the triggers 10 (AND) to a "similar state. Pa output of element 15 also generates a signal that changes There is a trigger state 12.

If after the digital (Russian) and Latin texts a combination of Russian letters (digits) comes in, the signal from the output 30 (32) of the decoder 19 through the switch 33 enters the block 21, prohibiting its operation, via bus 37 (39) - the trigger input 29 and changes its state, via bus 40 (41) to trigger inputs 10 (I) and element 14 (13). The trigger 10 (11) is reset, and the register combination is not formed on buses 23-28.

When the device operates on three registers with code L1TK-2, the switchboard is installed in

a position in which signals from the outputs 30 (32) of the decoder 9 are not generated at its outputs 34-42.
