 The device works as follows.

Turn on the power. The memory elements are set to their initial position, the trigger 16 is set to the first position (the output potential is a single potential).

The head (instructor) by pressing the 25 O and 26 1 buttons (without the arrival indicator) of block 2 enters into the register 18 binary codes of numbers, for example, 1 and 2 (0001, 0010). The code of one of the digits, for example, 2, depending on the position of flip-flop 19, through elements 21, the second inputs of which have a single potential from the second output of flip-flop 19, and the elements OR 22 is applied to the second inputs of the four-bit adder 5 and to the inputs of converter 36, which converts input code 8421 to output seven-segment code. The output code of the converter 36 is applied to the corresponding inputs of the indicator 38.

The device is prepared for testing.

The operator presses the Start key on the keyboard 53 of the console 9. The pulse from the output of the console 9 enters through the element I L AND 41 to the input of the counter 39, set the decoder 40 to the first position (at the first output of the group - the unit potential), to the first input of the generator 13, including the last, and through the element OR 17, to the input of the trigger 16. switching it to the zero position. The clock pulse from the generator 13 output through the prohibition element 15, to the control input of which zero potential is fed from the output of the trigger 16, is fed to the input of the pseudo-random sequence generator 12 and to the input of the delay element 32,

The binary combination from the output of the generator 12 through the encoder 14 is fed to the inputs of the converter 35 and to the inputs of the adder 5. The seven-segment code from the outputs of the converter 35 is applied to the corresponding inputs of the indicator 37.

A delayed pulse from the output of element 32 is fed to the input of the one-shot 30, causing a pulse with a duration of 2 seconds to appear at its output. The pulse from the output of the one-shot 30 is fed to the inputs of the formers 27 and 28 of single pulses (on the front and rear edges, respectively), to the control input of the adder 5, carried out summation and supply of the binary code from its outputs to the information inputs of the register 42, and to the control the inputs of indicators 37 and 38, providing the display of terms (numbers) for 2 seconds.

The operator visually captures the highlighted numbers, adds them in mind and remembers the amount.

A short pulse from the output of the imaging unit 27 is supplied to the inputs of the elements 33 and 45 and to the first control input of the register 42, having transferred the latter to the parallel recording mode. The delayed pulse from the output of the element 45 is fed to the second control input of the register 42,. providing parallel writing of the binary number from the outputs of the adder 5 to the register 42.

The delayed pulse from the output of the element 33 is fed to the input of the generator 31, providing the appearance at its output of a series of four clock pulses, which are fed to the third (clock) input of the register 42, moving the binary combination to the outputs of the first group. The code combination from the outputs of the first group of register 42 is applied to the first inputs of the corresponding elements AND 43m-43m, the second inputs of which are supplied with a single potential from the first output of the decoder 40. The binary combination from the outputs of the elements AND 43 through the elements OR 44 is fed to the first the inputs of the elements And 46.

A short pulse from the output of the imager 28, formed by the trailing edge of the pulse from the output of the one-shot 30, is applied to the input of the trigger 19, transferring the latter to the first position. The single potential from the first output of the trigger 19 is applied to the second inputs of the elements and 20, ensuring the passage of the code combination of digit 1 from the outputs of the first group of register 18 to the second inputs of the group of the adder 5. This same pulse applied to the counting input of the counter 64 potential at its first exit,

The impulse from the first output of the counter 64 p passes through the first input of the element AND 621, to the second input of which the unit potential is fed from the first output of the distributor group 6, and the element OR 63 to the input of the trigger 16, transferring the last one. A single potential from its output is applied to the control input of the element 15, cutting off the supply of a clock pulse from the output of the generator 13 to the input of the element 65 and to the input of the banner 66, highlighting the banner Answer.

The operator, seeing the glow of the banner Answer, on the remote control 9 searches for the key with the digit of the amount filled by it, for example, 7, and presses it. The pulse from the keyboard output 53 is fed to the input of the encoder 54e, providing a four-element binary code (code 8421) at its output, which through the OR 55 elements is fed to the second inputs of the group of block 8. At the same time, the polling pulse from the output of the OR element 56 is fed to the control input of block 8, by supplying code combinations from the outputs of the AND 46 and 47 elements to the corresponding inputs of the elements EXCLUSIVE OR NOT 48. In this case, the correct answer causes the appearance of a single pulse at the first output, and the wrong one at the second output of the block 8, to These are respectively fed to the counting inputs of the counters 57 and 58 of the block 10.

The delayed pulse from the output of the element 65 of the block 11 returns the counter 64 to the initial position, the banner 66 goes out.

The back edge of the polling pulse from the output of the OR 56 element causes a short pulse at the output of the imager 29, which through element 34 enters the input of the generator 31, the clock pulses from the output of which move information (binary code combination) in the register 42 from the outputs of the first group to the outputs second group.

After answering, the subject presses the keyboard key 53 The answer is completed, the pulse from the output of which through the element OR 17 is fed to the input of the trigger 16, shifting it to the zero position, to the input of the distributor 6, providing the appearance of a single potential at the second output of the group, and to the oblique input counter 58, returning it to its original state.

In the next cycle, two pairs of terms are presented. After the first pair is presented at the first output of the counter 64 of the block 11, a single potential appears (at the first input of the element 621), however, it does not pass to the output of the block 11, since from the second output of the distributor b the unit potential is fed to the second input of the element 11 622. The next clock pulse received from the generator 13 to the input of the generator 12 ensures the presentation of the second pair of terms, which are displayed on the indicators 37 and 38.

The operator visually fixes, adds the terms in his mind and remembers their amounts in the order of arrival, and when the transparency is illuminated, the Answer (after presenting the second pair of items) presses the keyboard keys 53 corresponding to the filled amounts (in numbers).

Thus, the presentation of two pairs of terms ensures the supply of information (code combination) to the groups of the comparison unit 8 from the outputs of the second group of register 42, the presentation of three pairs of the components — from the output of the third group, etc., t. e. The first press of any numeric keypad key 53 at the input of block 8 contains the control information (the sum in binary code) of the first pair of terms, the second press - the second pair, etc.

If the operator during the response in this cycle makes more errors, then the output of the counter 58 is an overflow pulse, which is fed to the second input of the generator 13, turning off the last one, to the input of the indicator 61, flashing the banner End, and to the control input of the key 59, giving a logical zero to the signal LEDs 60.

Using the illuminated LED 60 (its number indicates the number of pairs of terms presented in the last cycle) and the result of the readings of the counter 57 determines the suitability of the subject to the corresponding operator activity.

The use of the invention improves the quality of selection and expands the didactic capabilities of the device by taking into account the transformative abilities of the subject, caused by the processing of the presented information associated with the detection of RAM, by presenting (playing) a double test.
