the element ililll 22 and the element 23-delay.

The shaper 3 pulses between the signs includes an inverter 24, a one-shot 25 with an input delay, an AND 26 element and a shaper 27 of a short pulse.

readers 29, -29 (where m is a number of different characters), encoder 30, register 31, delay elements 32 and 33, OR-11E 34 and prohibition element 35.

The block AND recording of the results includes the first and second counters 16 and 37 and the first and second counters 38 and 39.

The display unit 14 has an indicator 40 number of errors and the indicator 41 the number of transmitted characters.

The synchronization unit 16 comprises a D-flip-flop 42, the first and second elements AND 43 and 44 and the element OR 45.

The simulator rotates as follows.

The switches 29 in the former 4 set the sequence of presentation of the characters in accordance with the beat of the radiogram, the controller on the generator 5 - the speed at which the telegraph operator works on the transmission of characters, and the controller on the time relay 10 - the time during which The radiogram is shown (controls are not shown). When the power is turned on, the counter-accumulator 28 is reset, the registers 17, 18 and 31, the counters 36 and 37, the trigger 8 is set to the zero state, the generator 5 is started (Fig.8a

The radio telegraph operator starts transmitting a radiogram consisting of 50 groups (250 characters).

When transmitting the first character (Fig. 8 of the text (the first element of the sign), the pulse from the output of the telegraph key 1 goes through element 6, to the prohibiting input of which zero potential is output from the output of the trigger 8 (Fig. 8b), to the one-shot input 7, causing the appearance at its output a short single pulse (Fig. 8d). This pulse is fed to the first (single) input of the trigger 8, a single potential and from the output of which goes to the third input of the block 16, sent clock pulses to

block 2, and is applied to the prohibitory input of element 6, preventing the next elements of the sign from entering the inputs of the one-shot 7, the counter-decoder 28 and the delay element 32 of the driver 4, providing the first output of the Morse code from the last output of register 31, corresponding to the first sign of the radiogram, and from the second output - clock pulses, respectively, on the first (fig.8e) and second (fig.8) inputs of block 2 and writing the sign in register 17 (the recording speed is 2 times greater than the speed of summer residence of the operator) and the relay 10 time input, carried it to run.

When a pause occurs (zeros on the last three outputs of the register 3l, v of fig.8z), a single potential appears at the input of element 34, which is applied to the inhibitory input of element 35, stopping the supply of clock pulses to the second input of unit 2. At the same time, the elements transmitted by telegraph key 1 of the character is fed to the input of the imaging unit 3 pause pulses between the characters and through the first input of the synchronization unit 16, the second input of which receives the clock (synchronizing) pulses from the depot 15, to the third input of the unit 2, to the fourth input About the clock pulses from the second output of the block 16.

The sign of the Morse code transmitted by the operator is recorded in register 18. At the end of the transmission of the first sign of the radiogram at the input of the driver 3, a pulse (pause) appears (Fig.8i), which arrives at the second input of the trigger 8, providing a zero output at its output potential (), which is applied to the prohibitory input of element 6 and the third input of block 16, stopping the supply of clock pulses to the fourth input of block 2, to the second input of block 13, writing one into counter 37, which through the corresponding input of the decoder 39 causes the left unit potential on the corresponding of the second inputs of the block 14, to the second input of the element 11, to the input of the delay element 9 and to the fifth input of the block 2 of the analysis of responses, providing with a small delay

(Fig. 8k) reading information from the inputs of registers 17 and 18 through the corresponding elements AND 19 and 20 to the inputs of the corresponding elements EXCLUSIVE OR 21.

If the operator correctly reproduced the sign, i.e. code combinations of characters recorded in registers 17 and

18 are the same, the zero potential does not change at the outputs of the elements 21, the zero potential at the output of the elements OR 22 (fig. 8l) 0

If the operator made a mistake in the transfer of the sign, i.e. combinations of characters recorded in registers 17 and 18 are not the same, then at the outputs of one or more elements EXCLUSIVE OR 21 a single impulse appears (Fig.8l), which through the element OR 22 goes to the first input of the result recording unit 13, writing unit The counter 36, which, through the corresponding input of the decoder 38, causes the appearance of a single potential at the corresponding one of the first inputs of block 14.

The delayed pulse (Fig. 8m) from the output of element 9 (the delay time of which is longer than the delay time of element 23 in response analysis block 2) goes to the sixth input of block 2, returning registers 17 and 18 to the initial state.

During at least three T, where Ј is the duration of the elementary parcel, the simulator circuit is prepared to control the next transmitted Morse code sign.

The same duration of the code sequence of the character supplied by the shaper 4 and transmitted by the operator is achieved by the appearance of a pause pulse in the interval between the characters, from 1.6 to 2.4.

When transmitting the next mark, the operation of the elements and units of the simulator is similar to that described.

After the time allotted for transmitting the radiogram, if the operator did not have time to transmit all the characters of the text, a single potential appears at the output of time relay 10 (FIG. 8n), which is applied to the first input of element 11. At the appearance of an output pause pulse shaper 3, which is fed to the second input of the element And 11, the pulse from the output of the element And 11 (fig.8o

through the element OR 12 is fed to the third input of block 14, highlighting on indicators 40 and 41 the number of errors and the number of transmitted radiogram characters, respectively (Fig. 8p)

If the operator is laid down at the set time for transmitting the radiogram text, then at the second output of counter 37 (with preset) block 13 a pulse appears, which through the element OR 12 enters the third input of block 14, illuminated in indicators 40 and 41 Errors and the number 250 (the number of characters in the radiogram), respectively. At the same time, a pulse from the output of the element OR 12 is fed to the input of a telegraph key and 1 and turns off the supply of voltage to it.

To transmit the next radiogram, it is necessary to turn off and turn on the device.
