0 counter 48 (incorrect answers - the first elements of the signal), counter 50 (the number of presented signals) and element 51 OR,

The device operates as follows,;

5 Preliminarily, in shaper 1, with switches 35, three-four-element signals (program) are dialed.

Turn on the power. Register 37, counter-decoder 34, and counters 14, 47 ... 50 are reset to their initial position.

Press the start button 29 on the remote 8. The pulse from its output through the element 15 OR is fed to the input of the counter 14, ensuring the appearance of a unit potential on it

5 first exit. Mode 1 is lit on indicator 21, instructing the test subject to present the first element (dot or dash) after the presentation of the signal melody and using the corresponding button

0 on the remote 8 to play it.

The output pulse of the counter 14 through the element 16 OR is applied to the element 18 And.

At the same time, the pulse from the output of button 5 29 enters through the OR element 42 to the input of the OR element 41 (Fig. 9a) and the input (on) of the generator 40. The clock pulse from the output of the generator 40 (Fig. 96) is fed to the input of the 41 AND element ( the pulse duration from the output of the button is longer than the duration of the clock pulse at the time the generator 40 is turned on), it comes from its output to the input of the counter-decoder 34 and the input of the delay element 38.

The pulse received at the input of the counter-decoder 34 causes a logical unit to appear at its output, which is supplied via the 35-hour switch to the corresponding input of the encoder 36 and ensures the formation of a signal corresponding to the one installed on the switch 35 in the form of a binary formalized number in which the point corresponds to 1, the dash corresponds to III, and the pause between the signal element is O,

The pulse from the output of element 38 enters one control input of register 37, transferring the latter to parallel recording mode, and passing through element 39 to another control input of register 37 provides parallel recording of a formalized binary number from the outputs of encoder 36 ( Fig. 9c). At the outputs of register 37, the first signal elements appear (Fig. 9d).

The pulse from the output of the delay element 39 through the element 18 And goes to the input of block A. ..- third inputs. Elements 25, 26 I.

Let the dash be the first element in the first signal (Fig. 9c). At the first three outputs of the register 37 - unit potentials (logical units) - Fig. 9d, 1-3, which are applied to the inputs of the elements 23, 24 AND, 28 OR, and 27 NOT. Two potentials of the elements 25 AND are supplied from the outputs of the elements 23, 24 And unit potentials, and to the element 26 And from the output of the element 28 OR, the unit potential is fed to only one input ..

Upon receipt of a single pulse from the output of block 3 to the input of block 4, the third inputs of the I 25.26 elements at the output of the 25 I element receive a pulse that arrives at the input of trigger 22, providing (confirming) the unit potential at its output, indicating that the first element of this signal is a dash (Fig. 9e, 1).

If the first element of the signal is a point, then at the first and third outputs of register 37 there are unit potentials (Fig. 9d, 13), and at the second - zero potential (Fig. 9d, 2). At the outputs of the elements 23, 24 And - zero potentials, at the outputs of the elements 28 OR and 27 NOT - unit potentials. At the inputs of the element 25 And - zero potentials, at the inputs of the element 26 And - unit potentials. Upon the receipt of a single pulse from the output of block 3 to the inputs of the elements 25.26 I / I at the output of the element 26 And a pulse is received which arrives at the input of the trigger 22, providing (confirming) the unit potential at its second output, indicating that the first element of this signal is a point (Fig. 9e, 2).

Therefore, if the first signal element is a dash, then from the first trigger output 22 to the input of the HE element 45i and the control input of the inhibit element 43i, a single potential is applied and from the second output of the trigger 22 to the input of the element 452 NOT and the control input of the inhibit element 432 - zero potential.

If the first signal element is a point, then the zero potential is applied to the input of the element 45i HE and the control input of the element 43i, while the second trigger 22 applies the unit potential to the input of the element 452 NOT and the control input of the element 432.

Upon completion of the signal extension, the zero potentials from the outputs of the register 37, applied to the inputs of the element 11 OR, do not cause a single potential to appear at its output (Fig. 9f), which triggers the one-shot 12. The pulse duration from the output of the one-shot 12 determines the response time ( Fig. 9g) and depending on the position of the switch is 3 s, 2 s or 1 s. The pulse from the output of the one-shot 12 is fed to the input of the remote control 8, applying a unit potential to the inputs of the response buttons 30-33, and to the input of the generator 40, turning off the latter.

The subject, after listening to the signal using the headphones of the electro-acoustic transducer 2 and recognizing its first element, for example, a dash, presses the corresponding button 30 (start, dash). The unit potential from its output goes to the information inputs of the elements 43i, 44i, to the control inputs of which from the first output of the trigger 22 the unit and zero potentials are supplied, respectively, due to the presence of the element 451 NOT at the input of the element 44. The pulse from the output of the element 441 passes through the element 46a OR to the input of block 10 and fix the correct answer in counter 47.

If the subject incorrectly recognized the first element of the signal and pressed button 31 (start, point), then the unit potential from its output will go to the information inputs of elements 43z, 442, to the control inputs of which from the second output of trigger 22 zero and unit potentials are supplied respectively for the presence of element 452 NOT At the input of element 44. Pulse from the output

element 432 through the element 46i OR passes to the input of block 10 and records in the counter 48 the wrong answer.

At the end of the response time, the trailing edge of the pulse from the output of the one-shot 12 arriving at the input of the driver 13 will provide a pulse at its output (the duration of which is equal to the pulse from the output of the Start button 29), which is fed to the input of the OR element 42 and to the input of block 10, having fixed the presented signal in counter 50.

The pulse from the output of the OR element 42 (Fig. 9a), similarly to that described, will provide a presentation to recognize the next signal.

After ten correct answers at the output of the counter 47, an impulse is received that enters through the element 15 OR at the input of the counter 14, providing a unit potential at its second output. After that, the counter 47 returns to its initial state. In the indicator 21, Mode 2 lights up, instructing the test subject to identify the last element (dot, or dash) upon completion of the presentation of the signal and use the corresponding buttons 32, 33 on the remote control 8 to play it. The pulse from the second output of the counter 14 through the element 17 OR is applied to the input of the element

19 I. Since at the moment the output of element 20 is OR NOT a zero potential (the next signal is being presented, the elements of which alternate at the fourth and fifth outputs of register 37), there will be no pulse at the output of element 19 AND.

When the last signal elements appear at the first., The third outputs of the register 37 at the fourth and fifth outputs of it, there are zero potentials, at the outputs of the element

20 OR NOT a unit potential (impulse), which from the output of the 19 And element is supplied to the inputs of the elements 25, 26 And, ensuring that the trigger 22 fixes the last signal element.

After ten correct answers at the output of counter 47, an impulse appears, which arrives at the input of counter 14, providing a unit potential at its third output. Mode 3 is lit on indicator 21, instructing the test subject to recognize the first and last elements of the signal upon completion of the presentation of the signal and

using the corresponding buttons 30, .. 33 to play them. The pulse from the third output of the counter 14, through the elements 16 and 17 OR, is applied to the inputs of respectively the elements 18 and 19 AND, providing the reading of information about the element of the beginning of the signal by the pulse from the first output of block 3 to the fourth input of block 4. and about the element signal end - with

0 the second output of block 3 to the fourth input of block 5. The operation of the elements of the device is similar to that described.

After ten correct answers in the third mode, counter 14 is set.

5 to the initial position, indicator 21 Mode is off.
