Block 11 of the presentation of information contains a shift register 56, the elements And 57 and 58, the element OR 59, the element BAN 60

and a scoreboard of 61, consisting of banners “Tone,” Wait, “Rhythm,” Goden and “Verification is over.

The device works as follows.

The subjects sit down at the tables on which the test consoles are installed, and are familiar with the instructions for their use.

The teacher on the remote control

turns on the power and enters "1" into register 39, sets generator frequency 1 to 900 Hz (if adjustable from 750 to 1050 Hz), and registers 40, sets generator pulse frequency 3 to 7 pulses per second

(when adjustable from 2 to 12 pulses per second). When the subjects are ready, the teacher presses the button 55 “Start.

The impulse from the output of the button 55 is fed to the inputs of the counters-detectors 36 of block 14, setting them to the first position (not shown) and including the banner “Tone on the display of 61 blocks of lli-lln, notifying the subject of the beginning of the test, to the first (single) RS input -trigger 49 block 5,

providing at its first output a single potential that enters the inputs of the elements OR 53 and 54. The single potential from the output of the element OR 53 enters the element 52 (the delay time of which is 3 s), and the single potential

from the output of the element OR 54 - to the second input of the element AND 50. The zero potential from the second output of the RS flip-flop 49 is fed to the prohibiting inputs of the elements ZAG1RET 41 and 42 of block 2, preparing circuits for passing pulses from the outputs of block 10.

The audio signal from the output of the generator 1 through the element 4, the second (controlling) input of which receives a zero potential from the output of the generator 6, passes through the element 50 of the unit 5 and the elements 57 of the blocks 11, the second (controlling) inputs of which act zero potential from the output of the element And 58, to the headphones 12 | - 12 ".

Subjects listen to the tone (frequency) of the signal coming from generator 1.

After 3 seconds, the pulse from the output of the element 52 turns on the generator 6, ensuring the supply of pulses from its output. The first impulse from the generator 6 with a duration of 3 s, received at the second input of the element I 4, closes the channel, stopping the flow

a sound signal to the headphones 12. This same pulse is fed to the input of the T-flip-flop 16 and the first input of the element And 19 of the block 10, preparing a circuit for changing the tone of the signal, and to the input of the differentiation element 8, the pulse from which

through diode 9 it enters the S-inputs of the flip-flops 21 and 22 of the 13i-13l blocks, sets the latter in one state, and to the first input of the block 14, fixing in the counter

The ke 32 is then presented for identification of the signal.

Let, when a pulse is applied from generator 6, trigger 16 is set to the first position and at its first input there is a positive potential, which is applied to the first input of element AND 17. When a pulse arrives from the output of sensor 20, the last through element 19 goes to the second inputs of elements Both 17 and 18. Since the first input of the element And 17 has a positive potential, the pulse from its output goes to the information inputs of the elements BANTS 41 and 43 of block 2. From the second output of the RS flip-flop 49 to the prohibiting inputs of the elements BANTS 41 and 42 served the zero potential, and from the first exit to the prohibitory inputs of the BANTS 43 and 44 elements - a single potential, therefore the pulse from the output of the element And 17 passes only through the element BANNER 41 to the first (summing) input, register 39 of block 2, advances "1 for one bit d, makes the connection of the next reactive element 46, through the element And 45, to the input of the generator 1 and provides an increase in the frequency of the latter by 10 Hz. At the same time, the pulse from the output of the element And 17 goes to the R-inputs of the flip-flops 21 in blocks 13i - 13l, sets the latter to the zero state and prepares the circuits for evaluating the responses. In blocks 13 from the output of the trigger 21, the zero potential is applied to the prohibitory input of the BANCH 24 element and the first input of the And 26 element, and from the output of the trigger 22, the unit potential is applied to the prohibitory input of the BANTH element 25 and the second input of the And 26 element.

At the end of the pulse from the generator 6 element And 4 unlocks the channel, and the signal from the output of the generator 1 with a frequency greater than 10 Hz, through block 5 and blocks 11 enters the headphones 12.

If the subjects distinguish the change in the tone of the signal, then press the button 29 "Above or button 31" Below, and if they do not distinguish, then button 30 "Has not changed.

If the subject correctly distinguishes the signal and gives an answer in the process of presenting the signal, then when the button 29 of the block 13 is pressed, a pulse from its output goes to the information input of the BANNER 24 element. Since the output potential of the 24 blocking input is zero, the pulse from its output through the element OR 28 enters the counter- deflector 36 of node 35, where the correct answer is recorded. At the same time, the pulse from the output of the button 29 through the OR element 27 enters the input of the element 23, and after the delay time has elapsed, the flip-flop 21 returns to the initial (single) state.

With similar actions of the other subjects, the same thing happens in blocks 13), i.e. from their outputs

single pulses in the corresponding counters-detectors 36 nodes 35 | -35 „| block 14, where the correct answers are recorded.

If the subject presses the button 31, the readings of the counter-decoder 36 do not change, since the prohibiting input of the element 25 has a single potential.

If the subject does not distinguish changes in the tone of the signal, he presses button 30. The pulse from its output goes to the third input of element 26, but since its first input has zero potential, the output 35n node 36 also fails to exit. does not change his testimony.

The similar actions of the other subjects cause similar phenomena.

If the subject gives an answer, i.e., presses one of the buttons 29-31 after presenting the signal, then there is no pulse at its output, since the output potential of the inverter 7 is applied to the inputs of these buttons. The response of the subject is recorded as incorrect. The triggers 21 and 22 then return to the one state until the test subject responds with a pulse from the output of diode 9.

In block 14, the number of correct answers of each subject and the total number of signal presentations to distinguish are recorded.

If the subject from among the 30 presented signals gives 24-26 correct answers, then the pulse from the second output of the counter-decoder 36 through the OR element 37 is fed to the register 56 of the block 11 and provides the supply of a single potential from its second output to the AND 58 element first After 30 impressions at the output of the counter 32 of the block 14, an overflow pulse appears, which is fed to the input of the indicator 33, fixing the number of presentations, to the input of the delay element 34 and returns the counter 32 to its initial state. After the delay time has elapsed, the pulse from the output of element 34 enters the second inputs of decoder counters 36 nodes 35 | -35, reads information into indicators 36, and then sets them to their initial state.

At the same time, the pulse from the output of the delay element 34 is fed to the second input of the generator 6, turning it off, to the second input of the generator 3, including it, and to the second (zero) input of the trigger 49 of block 5, providing the first output to zero, and the second output - single potentials. The zero potential from the first output of the trigger 49 through the element OR 54 enters the second (control) input of the element 50, stopping the flow of signals to the headphones 12 and the prohibiting inputs of the elements BANCH 43 and 44 of block 2, preparing the circuit for transition to the next mode. The unit potential from the second output of the trigger 49 is fed to the element 51

Delays on the prohibiting inputs of the BANKS 41 and 42, preventing further changes in the frequency of the generator 1, to the information inputs of the BAN 60 elements and the second inputs of the AND 58 elements, ensuring that the “Wait on the scoreboard 61” display of the corresponding subject is displayed.

If the subject of the 30 signals presented gives the correct answers to 23 (or less), then an overflow pulse from the output of counter 32 of block 14 arriving at the information input of the BAN 60 element of block 11, from its output passes to the entrance of the banner "Verification completed board 61, since the prohibiting input of the element BANGE 60 is applied to the zero potential through the element OR 59 from the outputs of the register 56 and illuminates it.

If the subject of 30 presented signals answered 27 (or more) correctly, then the pulse from the third output of the counter decoder 36 through the OR element 37 enters the input of the register 56, ensuring the supply of the unit potential from its third exit to the transparency Rhythm scoreboard 61 and through the OR element 59 to the prohibiting entry of the BAN 60 element. Transparency The rhythm is lit.

From the output of the generator 3 through the element OR 54 block 5 to the second input element And 50 receive rhythmic pulses. From the output of the element And 4 to the first input of the element And 50 receives an audio signal from the generator 1. From the output of the element And 50 rhythmic pulses filled with an audio frequency (rhythmic signal), through the element And 57 of the block 11 are sent to the headphones 12. signal in a certain (specified) rhythm, which they listen to and memorize.

After the delay time of elements 51 (1 3 6 s) and 52 (1 3 s), which increases the duration of the first rhythmic signal, so that the subject feels the transition to the next test mode, the pulse from the output of element 52 is fed to the first input of the generator 6 and turns it on. When a pulse arrives from the output of the generator 6 to the second input of the element AND 4, the supply of rhythmic signals filled with the tonal frequency is stopped. At the same time, the pulse from the output of the generator 6 enters the block 10 and, similarly to that described, provides a pulse from its outputs to the corresponding inputs of the block 2.

Let, for example, an impulse appears at the second output of block 10 (output of element AND 18). This pulse goes to the information inputs of the BANKS 42 and 44 of block 2. But since from the second output of trigger 49 of block 5, the prohibiting inputs of the BAN elements 41 and 42 are applied to the unit potential, and from the first output of trigger 49 to the forbidding inputs of

BANTS 43 and 44 - zero potential, then the pulse from the output of the element And 18 passes only through the element BANGE 44 to the second (subtractive) input of the register 40, advances

in it, “1 per bit, connects the next reactive element 48; through the element I 47 / to the input of the generator 3 and changes (lowers) the rhythm of the pulses (signals) presented. At the end of the pulse from the generator output 6 element

And 4 unlocks the channel and provides a tone to the headphones 12, the rhythm frequency of which has decreased.

If the subjects distinguish the change in the rhythm of the signal, then press the button 29

J or 31, and if they do not distinguish - button 30. After the first correct answer, the impulse from the output of counter-decoder 36 through the element OR 37 enters register 56 and translates it into the fourth position, while the banner “Rhythm continues to shine. The work of blocks, nodes and elements occurs as described.

If the subject of 30 presented signals gave 24 or more correct answers, then the impulse from the second output of the counter decoder 36 translates the register 56 into the fifth position, extinguishes the “Rhythm” banner and ensures the “Transmit.

After the presentation of the thirtieth signal

“The impulse from the output of the counter 32 reads out the correct answers in the indicators 38 and, having entered through the element BAN 60 at the entrance of the banner“ Verification is over, flashes it. Subjects in whom the banner reads "Fit for" is considered suitable for teaching the specialty of the radio telegraph operator. Based on the indications, the indicators judge the possibility of re-checking by rhythm. Subjects with a transparency “Wait, re-test for discernment

0 frequency (tone) signals.
