Indicator 10 contains a descrambler 47 and indicator 48,

The device works as follows

Turn on the power. The counter 20, registers 3 and 4, the distributor 9 are reset, and the trigger 39 is in the zero state. Using the buttons 33 (without the detector), a test (training) program is made, for example, to find (mark) the numbers in the sequence: the first (01) is green, the second (24) is red, the third (02) is green, the fourth (23) is red, the fifth (03) is green, the sixth (22) is red and forty-seventh (24 ) - green, forty-eighth (01) - red, forty-ninth (25) - green.

When the button 33 is pressed, a single impulse from its output is fed to the corresponding input of the encoder 34, a binary combination corresponding to the code number appears at its outputs. At the same time, the pulse through the OR 43 element goes to the controls of the input indicator 48 and to the input of register 3, made the transfer of the latter to the parallel recording mode, and having passed through the delay element 40, is fed to the input C of the register 3, ensuring parallel recording of the formalized binary number, from the output of the encoder 34 to the register Zo On the indicator 10 lights up 00, signaling that it is in its original state.

The impulse from the output of the element 40 through the information input of the element 36 prohibition, the control input of which has zero potential from the output of the element OR 14, and the element OR 44

given to the input of the generator 35, causing the appearance of a series of eight clock pulses, which through the prohibition element 37, to the control input of which the output potential of the element OR 45 is applied to zero, are fed to the input

From register 3, shifting the binary code combination from 1-8 bits (last group output) to 9-16 bits (the penultimate group output). The binary combination of the number from the register 3 output goes to the decoder 47 inputs in the indicator 10, the output code of which is fed to indicators 48. The number 00 is replaced by the number 01, confirming that the first number has been entered correctly.

The next pressing of the button 33, records and advances through the register 3 binary information, the code of which corresponds to the number 24, so that on the indicator 10 the number 01 changes to a number. Further program input is performed similarly.

When you enter the penultimate number of the program after displaying the number .01 on the indicator 48 of node 10, a single potential is applied to the control input of the element 36 from the first bits of register 3 (the first output of the group)

Pressing the 33j5 button of the last program number does not change the light of the monitored number 01 on the display 10, a warning about the end of the program input

After the program has been entered into register 3, the latter is rewritten into block 6 in order to predict numbers in random order. For this, the test presses the button 26. The impulse from its output, entering the input of timer 11, sets the latter to the initial position, starts: the one-shot 19, the unit potential from the output of which flips the trigger 39 to one, enters the input of the imager 38 and the input of the element And 22, ensuring the passage of pulses from the output of the generator 18 through the elements OR 24 to the input of the counter 20, transfer the latter to a random state. At one of the outputs of depistrator 21, corresponding to the given random state of counter 20, when a pulse arrives at its control input from the output of the imaging unit 38 (upon termination of the pulse from the output

one-shot 9,) in terms of unit potential, which goes to the corresponding input of node 2 - to the input of the former 27, element 30 and the prohibition element 29 The unit potential (pulse) from the output of element 29 through unit 13 enters the input of block 8 - the second inputs of the corresponding And 54 elements, to the third inputs of which, through the OR 60 element, from the output of flip-flop 39, a single potential is fed, and the binary inputs from the outputs of the register groups are fed to the first inputs

Code combination from the given random exit of the group (elements AND 54) through the elements OR 55 and the element; 58 of the prohibition, on the control inputs of which the zero potential is fed from the output of the ICH-15 element, is fed to the information inputs of the register 4,

The rear edge of the pulse from the output of the single-emitter causes the appearance at the 5th output of the shaper 38 of the short pulse, which enters the input of the register 4, having transferred the latter to the parallel recording mode, and the delay element 41 passes to the input C 2 of the register 4, ne4iiB parallel zap. : s binary information (code) from the outputs of the register 3 B register 4 about

A pulse from the output of the element 41, fed through the element OR 44 to the input of the generator 33, results in a series of eight clock pulses at its output, which through the element 42, to the second input of which the unit potential is fed from the output of the trigger 39, is fed to the input C, register 4; by moving the binary combination from 1–8 to 9–16, and entering through the prohibition element 25 and the OR element 23 to the input of the one-Vibrator 19 starts the last one, removing the unit potential from the output of the former 27, causing the appearance of it pulse output that translates trigger 28U single state, and Collateral chgvva recording into register 4 the next random number :,

If the random signal is re-wired at the same output of the dep T-Tfrator 21, then the IZO element, to the second input of which the unit potential is fed from the output of the trigger 28, passes to the input of the OR 32 element. 5 {mppuls from the OR element 32 output

will shift the contents of counter 20 by one bit. This movement will occur until an unused decoder output of 2 s is detected, the Uniform potential applied through the OR element 31 to the control input of the prohibition element 29 prevents the binary combination from the outputs from being re-read surveyed register groups

When a code combination appears at the outputs of register 4, the unit potential is fed through an element 15 of the ShH 15 to the input of trigger 39, transferring the latter to the zero state and preventing the last binary combination from advancing to the control input of the element 25, blocking the trigger pulse path to the input of the one-oscillator 19, the control inputs of the prohibition element 58, blocking the information inputs of the register 4, through the element OR 45 to the control input of the element 37, blocking the output of the generator 35 (to the register 3), to the input of the imager 62, a short pulse From the output of which sets the counter 12 to the initial state, and to the input of the key 16, applying the ignition voltage (a single potential) to the control inputs of the indicators 48 of the unit 6 о The single potential from the output of the key 6 starts the timer S1,

The subject is presented with a scoreboard of two-digit luminous numbers on the indicators 48 of block 6 placed in random order, green ones - from 01 to 25 red - from 01 to 24 "

In accordance with this program, the test finds the number 01 - green and presses the switch 53 button 7 above it. The impulse from its output allows the code combination from the corresponding group of outputs of register 4 to pass through the AND 49 elements and the OR 50 elements to the outputs of the switch 7. Coding The combination of this number from the outputs of the switch 7 is fed to the input of block 8 — the first inputs of the AND 57 elements. At the same time, the pulse from the output of button 53 through the element OR 52 starts a single-vibrator 51, the pulse from whose output is fed to the input Soliter 9, having ensured the appearance at its first output of a single potential, which through the block 3) enters the second inputs of the elements And 54, block 8

If the number of subjects is correctly determined by the subjects at the outputs of the elements of the IS-KEYWORKE OR 56, the potentials are zero, the output of the element OR 61 is zero; if the answer is incorrect (determining the number), unit potentials appear at the outputs of elements 56, and at the output of element 61 there is a single impulse that arrives at the input of counter 12, fixing the wrong answer.

When you press the button 53 of the last number at the output of the distributor 9, the pulse that arrives at the input of the register 4 is set, bringing the last one to the initial state. The zero potential from the output of the element OR 15 closes the key 16, the numbers on the indicators 48 of block 6 go out, the timer 1I fixes the time for determining the numbers Counter 12 will record the number of incorrect answers
