The simulator works as follows

In advance, the switch teacher sets the spacing of the pulses of the generator 28 corresponding to a certain transmission rate, for example 6 Gy / min, and the duration of the pulses of the driver 17, for example, 10%, with which the learning of 1Mo

Turn on power. Counters 10, 15 and 52 - 55 are reset. The device is ready for operation.

When the trainees are ready for text transmissions according to the master method, the teacher presses the start 18 button. The impulse from the output of the former 18 is fed to the input of the control unit 5, writing 1 to the first (zero) register register 42, and through the OR 33 element to the input of the delay element 26 and the input of the distributor 34, ensuring the appearance at its first output of a single potential The unit potential from the first output of the distributor 34, through the switch 35, is set to, for example, the letter A, is fed to the inputs of the encoder 24, providing the output on its outputs of the specified character in the form of a binary formalized number, in which the point corresponds to 1, a dash 111, and the pause between the elements of the character

The pulse from the output of the delay element 26 is applied to the delay element 27 and the first control input of the register 25, transferring the latter to the parallel recording mode, and, after the delay element 27 goes to the second control input of the register 25, ensuring parallel recording of the sign from the output encoder 24 to register 25o

The clock pulses from the generator 28 output, fed to the clock input of the register 25, advance the sign from the (n + 2) -th output to the control input of the key 30 and to the first input of the EXCLUSIVE BLM 58 element

(figo8a).

The first element of the sign A (point) with

key output 30, filled with frequency5

generator 3, through the element OR 57 is fed into the electroacoustic transducers

The trainees, in accordance with the text, transmit the first character (A), the manipulator with a telegraph key 1

When forming the first element of the sign (point), the positive potential from the output of the telegraph key 1 is fed to the second input of the EXHIBITOR OR 58 element and to the control input of the key 56, ensuring the passage of the audio frequency from the generator 9, which is selected at 100-200 Hz or below the oscillator frequency 31 This signal through the element OR 57 is also fed to the electroacoustic converter

If the student transmits the elements of the sign with a delay (figvBb) or advance (figoVv) with respect to the elements of the sign of the leading signal, then in the electroacoustic converter 3, characteristic claps are heard that follow a uniform tone.

At the same time, the code combinations of the master and slave signals (signs) fed to. The first (from the output of register 25) and the second (from the output of the telegraph key 1) elements of the element - EXCLUSIVE ШШ 58, generate at the output pulses whose duration is determined by the time delay (figv) or advanced (figv) the slave formed by the student, which are fed on information

elemental (first) inputs of elements And 4447,.

Clock pulses from the output of the generator 28, the duration of which is equal to the duration of the elementary sending (point) of the leading signal, are fed to the differentiation unit 16 and the leading edge of the incoming clock pulse generates an odd pulse, the trailing edge - an even pulse that is fed to the driver 17, which forms positive pulses of a specified duration and with a corresponding shift-delay (depending on the position of the permissible error switch - 5, 10, 20% of FIG. 8)

a pulse, which is supplied respectively to the inputs of the first and second shaper 37 and 38 short pulses, forming pulses of rectangular shape (fig8), 200 μs long

Let the head need to control the beginning of the transmitted elements of the sign, then he turns on the button 22 Start of the console, Toe delivers unit potentials to the control (fourth) inputs of the first and second elements And 44 and 45 o

A pulse (odd) from the output of the driver 37 is applied to control (third) inputs of elements And 44 and 46 and through element HJDi 39 to the first input of generator 43, the last one starts. Clock pulses from its output of a frequency of 1 kHz. served on

the shift input of the register 42, ensuring the sequential movement of the previously recorded 1 by its discharge and the supply of a single potential (impulse of the Poll) to the control (second) inputs of the And 44 - 47o elements

Therefore, if the trainee began to transmit earlier (figv) than the master (control) signal arrived

35 cash (figo8a), while exceeding the set tolerance time, then when an odd pulse arrives Poll from the register output 42 at the output of the AND 44 element is given a pulse that will pass through the OR 48 element

to the input of the counter 52 and will record the advance of the transfer of a given element of the sign to the corresponding trainees at its beginning (fig8) (,

If the beginning of the transfer of the elements of the mark does not exceed the established tolerance, then when a pulse arrives Poll from the output of register 42 at the information (first) input of elements AND 44 - 47 the unit potential

With the occurrence of 1, at the zero output of the ring register 42, a pulse is formed at the output of the one-shot 41, which will go to the second input of the generator 43 and turn it off;

transmission of pulses from its output is stopped

An impulse (even) from the generator output is fed to the control (third) inputs of even elements 45 and 47 and through the element OR 39 to the first input of generator 43, by running the last sync pulse from the output of generator 43 to provide pulse A survey on the control (second) inputs of elements I 44 - 47 °

If the learner began to transmit later (figb), than the control signal arrived, and exceeded the tolerance time, then at the information (first) input of AND 44 - 47 elements there is a single potential from the first run of unit 2 (fig.8g). When an even pulse arrives register 42 at the output of the element AND 45 in accordance with the Wits pulse, which through the element OR 49 enters the input of the counter 53 and will record the delay of the transfer of the element of the sign at its beginning (fig8i)

To control the ends of the transmitted elements of characters, the head includes a button 29 Ends, Toi delivers unit potentials to the control (fourth) inputs of the third and fourth elements And 46 and 47

If the student completed the transfer of the character element before the end of the incoming leading (control) signal (figo, c), and exceeded the tolerance time (figs8d), then when an odd pulse arrives, a poll from the output of the register 42 at the output of the element 46 which through the element OR 50 will go to the input of the counter 54, fixing the advance of the transfer of this element of the sign at its end (figs)

If the student has completed the transmission of the sign element after the termination of the incoming driving signal (Fig. 8.6 and exceeded the tolerance time (Fig. 8d), then upon receipt of an even pulse. Poll from the register output 42 at the output of the element 47 a pulse, which the element OR 50 will arrive at the input of the counter 55, fixing the delay of the transfer of the element of the sign at its end (figs) o

If the end of the transmission of the elements of the sign does not exceed the established tolerance, then when a pulse arrives, a poll from the output of the register 42 at the information (first) inputs of elements I 44 - 47 does not have a single potential (there will not be any at the pulse outputs)

Every five seconds, in block 8, the percentage of delays (advances) in the beginnings and ends of the elements of the signs of

At the end of the sign, at the outputs of register 25, zeros appear, which, acting on the inputs of the element OR NOT 29, cause the appearance at its output of a single potential - a gap pulse, which is fed to the input of trigger 14, ensuring the appearance of a single potential at its output potential

Control by the teacher of the transfer of individual trainees is carried out as follows.

The teacher on the switch 21 of the console 7 presses a button (not shown) that corresponds to the student being monitored, for example, workplace No. 2. Positive potential from the second output of the switch 21 through the element OR 12 is fed to the one-shot 13 (with potential input). Pulse from the output the single vibrator 13 is fed to the input of the trigger 14, ensuring that a zero potential appears at its output (to start counting the number of characters from the next character), and to the inputs of counters 0 and 15, setting them in the initial state o

When a pause pulse arrives at the trigger 14 input from the second output of block 6, a single potential is applied at the input of the trigger 14, which is applied to the second input of the AND 20 ° element. If the transmission of the slave signal does not coincide with the leading signal, then the EXCLUSIVE OR 58 output (workplace No. 2) according to Vits pulse error, which through the switch 21 and the element I 20 will go to the information input of the element 19 prohibition

If the duration error pulses do not exceed the tolerance pulses coming from the output of the imaging device 17, then there will be no error pulses at the output of the element 19. If the duration error pulses exceed the tolerance pulses, then at the output of the element 19 in ts, the error pulses

An error pulse from the output of element 19 transfers the trigger 23, which is set to zero position by a pause pulse, to a single position. The impulse from the output of trigger 23 arrives at the first input of counter 10 and will fix the sign transmitted with an error. The pause pulse from the output of element 29. to the inputs of the trigger 23 and

14, will transfer them to the zero position, and, entering the first counter input

15, will fix the transmitted character

Upon completion of the control, the teacher returns the switch button 21 (of workplace No. 2) to the initial state, the flow of information from the output of the item EXCLUSIVE OR 58 stops

By switching on the control of the next 20 trainee (pressing the Indicator button is not shown), the pulse from the output of the one-shot 13 returns the counters 11 and 15 to the initial state and release.
