The simulator works as follows,

Tutorial P1: it is possible to listen and play through a response input block (keyboard) a specified sequence of Morse code characters, and the playback and perforation operations are shifted in time one relative to another by an interval multiple of the length of one, two or three Morse code, which can vary with ycnejn-carry workouts.

The sequence by the Morse code symbol for presentation is formed in block 18 of the diagram. In counter 37, the permissible number of errors (for example, three) per 100 characters is set.

Turn on the power. The registers and counters are reset.

When a button is pressed. A trigger (not shown) impulse from its output enters 5 register 10 input,

the latter in the first position and ensuring the appearance at the input of the element I 14 of a single potential, and the input of the generator 1, ensuring the appearance at its output of the first sign of the Morse code of a given sequence in the form of a binary formalization combination, which, using an electroacoustic converter 4, is converted into a sound signal presented to the student. At the same time, the sign combination is recorded in register 11 and entering through element AND 14 and element OR 17 into register 13. This same sign goes into pause extraction block 5, which After the end of the sign, it forms a pulse (the pulse of the pause between the characters). This pulse arrives at the input of the driver 3, ensuring the formation of

a short pulse, to the input of the register entry 27 of block 6, ensuring the parallel recording of information into it from the outputs of the register 13, and to the input of the delay element 8. The pulse from the output of element 8, delayed by the time required for the census of information and preparation for issuing the next character, arrives at the input of register 13 and returns it to its original state. In block 2 of the display on the banner, the light responds and the G pointer, Pointer 1 indicates that the interval between listening and playing is equal to one character.

When a banner fires up Answer a student with the help of iciatura- tion of block 9 reproduces the first symbol of Morse code heard, and at this time the second symbol is applied to the electroacoustic converter 4. The code combination of the character from the first output of block 9 is fed to the input of block 6 and is written to register 28. At the end of the code combination, from the output of block 9, a pulse is sent to the input of block 6 Polling. Code combinations of characters in the form of 1 and o from the outputs of registers 27 and 28, attached to the first inputs of elements I 29, 29c and 30–30 c of the first and second groups, when a pulse arrives. A survey of their second inputs goes to the corresponding inputs of the elements. Equivalence 31, - ZTS.

If the code combinations recorded in registers 27 and 28 are the same, then when a pulse arrives, a poll appears at the output of element 34 and a pulse appears that goes to the counter 36 of block 7 and records the correct answer.

If the code combinations recorded in registers 27 and 28 are not identical, then after a pulse has been decelerated Poll, an output appears at the output of the element HE 33, which arrives at the counter 37 and records the wrong answer. At the same time, the zero potential from the output of the multi-input element And 32 enters the input of the element And 34 and prevents false triggering.

Pulse Poll through the delay element 35 is also fed to the inputs of the Set to zero registers 27

and 28 and returns them to their original position.

After completing the presentation of the second character, block 5 again forms

interrupts the impulse of a pause between signs and so on, i.e. the work of the blocks, knots and elements of the simulator, when presenting and responding to each subsequent sign, occurs

0 described above.

In this mode, the simulator works until the student reproduces the entire cycle (100 characters) without errors or exceeds the specified

5 level of errors.

When the hundredth character is transmitted, the counter 36 overflows and the overflow pulse enters the input of the register 10, transferring the latter to the second

0 position and ensuring the appearance at its second output of a single potential, which is fed to the input of the element 15.

After the end of the presentation

5, the hundredth sign of the pulse from the output of block 5 is fed to the first input of block 2 of the display, causes a fire on the banner Answer and pointer 2. The first flashing numbers

Q 2 (as well as 3) is duplicated

a short background signal (not shown) and indicates that in this cycle this sign is the last, i.e. after the response of the learner, the device enters the second mode, in which the learner must respond with a delay of two characters. At the same time, after reproducing the last character of the cycle, the next (first) character will be recorded only in memory register 11, since the unit potential at the second input of the And 14 element is absent. Register 13 is in the initial state, so when the next light is on the banner Answer, after the presentation of the second character, the learner does not take any action. The next (second) sign of the sequence (after the hundredth sign

 k) is written to register 11, having read the previously written first character from it, through the AND 15 element and the OR 17 element, and the last one is written into the register 13.

5 Upon completion of the recording of the second character and the census of the first, i.e. when a pause pulse arrives, the character combination from register 13 will be overwritten into

five

register 27 of block 6 with a delay of two characters and with the subsequent ignition of the banner Answer the student reproduces the sequence character with a delay of two characters, i.e. when presenting the third character. The operation of the other units of the simulator is similar to that described above for the first mode.

If the student in the second cycle does not exceed the allowable number of errors, the simulator switches to the third mode, in which the interval between listening and playback is three characters. This is achieved by moving the register 14 to the third position and connecting the register 12 through the element AND 16 and the element OR 17 to the register 13.

When a student learns in a process of a specified number of opshbok counter 37 overflows and the pulse from its output turns on the indicator

Mistake. This serves as a warning to the learner and his relaxation, and requires increased attention or cessation of work for some time in order to restore normal functional condition.
