The same contains block 2. The block consists of three parts 16-18. each of which provides a comparison of a single digit code combination.

Block 3 consists of the first and second 19 and 20 delay elements, the first and second elements OR 21 and 22. The counters 23 and 24 are the number of software operations, respectively, exact (three) and inaccurate (two) matches of the numbers with the control, first and second counters 25 and 26 crossings, respectively, exact and inaccurate coincidences, the counter 27 is the number of lines, and elements 19 and 20 provide separate supply of pulses to counters 23 and 24 from the second block 5 of program operations.

Switch 6 contains the first and second RS-triggers 37 and 38. the first to the sixth elements And 39-44.

Remote 7 has indicators 45 and 46 Control and Information, respectively, button 47 Line counting down the transition to the next line, button 48 Full match and button 49 Incomplete match.

Block 8 contains a differentiation element 50, a divider 51 into two. the first and second elements And 52 and 53. the first and second

the elements OR 54 and 55, the first and second counters 56 and 57 (with an adjustable counting cycle), the first and second one-shot 58 and 59, a short pulse shaper 60 and

RS flip-flop 61.

Block 9 includes decoders 62i ... 62io and indicators 63i ... 63io.

The shaper 10 contains an OR 64 element, an RS flip-flop 65, a clock pulse generator 66, a delay element 67, a generator 68 pseudo-random sequence (SRP), a shift register 69, a prohibition element 70.

The device works as follows.

Turn on the power. The triggers 37, 38 and 65 are set to one, and the trigger 61 is set to the zero state, the registers and counters are reset, on the gun 7, the Control indicator 45 lights up.

A single potential from the output of the trigger 65 starts the generator 66, the clock pulses from the output of which (fig.-Ju) are fed to the input of the counter 56 of the block 8 and

5 through element 67, the delay time of which is equal to the sum of the response time of the counter 56, the element OR 54, and the one-shot 58, to the information input of the prohibition element 70. Since zero potential is supplied to the control input of the element 70 from the output of the one-vibrator 58 of the block 8. The clock pulses pass through the element 70 (Fig. 106) to the input of the PSP generator 68 and to the input Ci of the register 69. Binary sequence

5 from the output of the generator 68 (Fig. 10c) is fed to the input Vi of the register 69. recording in it the clock pulses applied to the input Ci from the output of the element 70.

At the same time, the binary sequence and clock pulses through the elements And 39 and 40 of switch 6, the second inputs of which are fed to a single potential from the first output of the trigger 37, go to the first inputs of the elements 41–44 respectively. A single potential coming from the first output of the trigger 38 to the second inputs of the elements 41 and 42. ensures the passage through them of a binary sequence and a clock

0 pulses. The binary sequence from the output of the element And 41 is applied to the input Vi, and the clock pulses from the output of the element 42 to the input Ci of the register 11 of block 1, ensuring the record in the last pseudo-random

5 sequences.

When the thirteenth clock pulse arrives at the input of the counter 56 of block 8, an overflow pulse appears at its output (Fig. South), which is fed to the input of the one-shot 58 and starts the last

(Fig. 10d). A single potential from the output of the one-shot 58 is fed to the input of the differentiation element 50 and through the element OR 54 to the control input of the element 70 of the driver 10, stopping the flow of clock pulses (Fig. 106) to the input of the generator 68, the input Ci of the register 69 and the input of the element 40 switch 6, i.e. delaying the extension of the binary sequence from the output of the generator 68 and suspending its movement in registers 69 and 11.

The front of the pulse from the output of the one-shot 58 block 8 provides the appearance at the first "output of the short pulse element 50 (Fig. 10e), which is fed to the input of the divider 51. The falling edge of the pulse from the output of the one-shot 58 causes the appearance of a short pulse at the second output of the element 50 (Fig. 10g), which is fed to the R input of the trigger 38 of the switch 6, transferring it to the second position (at the second output unit potential) and to the converting input of the counter 56, returning the latter to the initial position.

The appearance at the control input of the element 70 of the former 10 of the zero potential from the output of the one-shot 58 provides clock pulses from the output of the generator 66 through the element 70 to the input of the generator 68, the input Ci of the register 69 and through the element 40 and to the inputs of the elements 42 and 44. Since a unit potential from the second output of flip-flop 38 is applied to the second inputs of And 43 and 44, the binary sequence and clock pulses from the outputs of And 43 and 44 are respectively fed to the Vi and Ci inputs of register 11 of block 2, ensuring that the binary code is written to itcombinations, similar to those recorded in register 69 (Fig. 10c).

When a block 8 arrives at the counter 56 of the thirteenth (after reset) clock pulse, an overflow pulse appears on its output (FIG. South), which starts the one-shot 58 (FIG. Yod). A single potential from the output of the one-shot 58 is fed to the input of the element 50 and through the OR 54 element to the control input of the element 70 of the former 10. By delaying the pseudo-random sequence from the output of the generator 68 and suspending its movement in register 69 and register 11 of block 2.

The leading edge of the pulse from the output of the new vibrator 58 provides for the appearance at the first output of the element 50 of the pulse (the second) (Fig. 10e), which is fed to the input of the divider 51, ensuring the appearance of a single pulse at its output (Fig. Yuz).

The pulse from the output of the divider 51 through the element 53, to the second input of which a unit potential is given from the second output of the flip-flop 61, is fed to the input of the one-oscillator 59, ensuring that a pulse with a duration of 2 s appears at its output (the time of control numbers memorization) ( Fig. 10i). which is applied to the R input of trigger 37 of switch 6, ensuring that its

0 zero potential output through the OR 54 element to the control input of the element 70, stopping the supply of clock pulses for the time of presentation of the control numbers, and through the OR 55 element of the block 8 - to the 5 control input of the block 9, highlighting two three-digit indicators on the 63i and 632 indicators the numbers that the subject must remember.

The zero potential from the output of the trigger 37 disables the switch 6, fixing in

0 registers 11 blocks 1 and 2 control code combinations (program numbers).

A short pulse from the second output of the element 50 of the block 8 (Fig. 10g) is fed to the embedding input of the counter 56, returning

5 it is in its original state

The rear edge of the pulse from the output of the single-vibrator 59 (Fig. Yui) will form a short pulse at the output of the imaging unit 60 (Fig. 10k), which, arriving at the S input of the trigger 60, ensures the appearance of a single potential at its first output. The unit potential from the first output of the trigger 61 is fed to the second input of the And 52 element, preparing a circuit for passing the pulses of the end of the number from the output of the counter 56 to the input of the counter 57 and to the input of the indicator 46 Information of the remote control 7, notifying the subject of the presentation of information (random three-digit numbers) in

0 of which he must reveal the filled control numbers, as well as numbers containing two check digits each.

The zero potential from the second output of the trigger 61 is applied to the second input of the element And 53, warning the possibility of the subsequent launch of the one-shot 59.

The appearance of a zero potential at the control input of the element 70 (Fig. Yui) ensures the passage of clock pulses from the output of the generator 66 (Fig. 106) to the input of the generator 68 of the memory bandwidth and to the input Ci of the register 69. And the binary sequence from the output of the generator 68 to Vi input of register 69 by writing code combination

5 in the latter (Fig. 106, c).

At the same time, the code combination from the outputs of the first subgroup of register 69 is fed to the first inputs of elements 12 of logical groups 16-18 of blocks 1 and 2.

Fixing the thirteenth clock pulse by the counter 56 (after another reset) provides the appearance of an overflow pulse at its output, which triggers the one-shot 58, and through the element 52 it is applied to the input of the counter 57. registering the presentation of the first row number. A single potential from the output of the one-shot 58 stops the advancement of the binary sequence in register 69 and causes the appearance of a short polling pulse at the first output of the element 50.

The code combination from the outputs of the first subgroup (the first to the twelfth outputs) of register 69 is applied during the period of one clock pulse to the first inputs of the corresponding elements AND 12 of blocks 1 and 2 (each digit of the number is represented in the four-element binary code).

The polling pulse from the third output of block 8 is applied to the third inputs of blocks 1 and 2, the second inputs of elements 12 and 13. If the code combinations attached from the outputs of the first subgroup of register 69 to the first inputs of elements 14 match, the code combinations attached from the outputs of registers 11 to the second inputs of the elements 14, at the outputs of the latter there appear single potentials, and if there is a discrepancy, the zero potentials that arrive at the inputs of the elements And 15 of their group.

If all three digits in the number match, i.e. in the information binary sequence there is a program number (check), then single pulses from the outputs of the elements 15 of block 1 and (or) 2 are fed to the inputs of the corresponding elements 28-30 of blocks 4 (5). the delay of which is equal to the response time of the AND 36 element and the inverter 32, and the inputs of the AND 36 element. The pulse from the output of the AND 36 element enters through the inverter 32 to the third inputs of the AND elements 33-35, preventing the appearance of pulses at their outputs, and through the OR element 21 blocks 3 - to the input of the counter 23, fixing the presence of an exact program of the operation (check number). ,

If two digits in the number match, then at the output of the AND 36 element the zero potential does not change. A single potential from the output of the inverter 32 is applied to the third inputs of the And 33-35 elements.

If there is a coincidence of digits (pulses), for example, at the first and third inputs of block A and (or) 5, the pulse at the outputs of element 28 is fed to the first input of element 33 and the second input of element 34, and from the output of element 30 to the first input element 35 and the second input of element 23. At the output of element 33, an impulse appears, which

through the element OR 31 enters the input of the element OR 22 of block 3. A pulse from the output of the element OR 22 is fed to the input of counter 24, registering the presence of an incomplete (accompanying) program operation (a three-digit number coincides with two digits).

When a single digit in the number at the output of the element OR 31 pulse is missing.

After filling in the register 69 of the binary PRD of the tenth three-digit number, an overflow pulse appears at the output of the counter 57 of block 8, which enters the R input of the trigger 65 of the driver 10 and turns off the generator 66, stopping the clock pulses (Fig. 10a ).

At the same time, the unit potential from the output of the counter 57 through the element 55 enters the control input of the block 9. Ensuring the display of the indicators 63 — strings of ten three-digit numbers (FIG. Yui).

The subject, comparing each three-digit number of the presented string with two three-digit numbers filled in, reveals and counts numbers that match three digits, and separately numbers that match two digits, pressing the corresponding buttons 48 and 49 Full match and Incomplete match so many times how many similar matches per line.

Let the line contain one complete and three incomplete matches, then the test button 48 presses one time and the button 49 three times. In this case, a unit is recorded in the block counter 25, and three in the counter 26.

At the end of the response, the subject presses the button 47 String, the pulse from the output of which is fed through the OR 64 element to the S input of the trigger 65. by running the generator 66 and the counter input 57, returning it to its original state.

The formation of the second (next) line is carried out in a similar way.

The amount of RAM of the subject is determined by the ratio of 2 m.

where t is the number of figures correctly crossed out by the subject;

N is the total number of program numbers.
