that the elements entered provide dg 40 and the numbers on them, which received

when you repeatedly press the Exposure button to see the correct and incorrect answers, the correct answers will be accompanied by an intermittent luminescence of the indicators at a frequency that determine the control signals from the registers 21. The subject visually fixes both the numbers and the placement of the indicators 40, on which these figures are highlighted. Then it reproduces the stored information, the frequency of the generator 10 clocks 50 presses on the button 39 of the illuminated indications and the division factor of the delicator 40 and the button 41 of the digital row, corresponding to 42 frequencies.

The device works as follows.

After turning on the power, they press the button “Setting to“ About in block 1 (not shown), starting this generator 9, the output of which goes to the inputs of register 14, counter 16 and registers 21,

corresponding to the highlighted digit on the indicator 40. Pressing the button 39 switches the outputs of the corresponding register 21 from the indicator 40 to 55 elements AND 32 of the block 7. If this indicator 40 displays a sti.mul, then the input potential of one of the elements is 32 . When the inputs of the counters 34 and 37 are correctly reproduced, the inputs for setting the triggers 45 to the zero state (not shown) set them to the initial (zero) state. In register 27, one is entered. Switches 17 and 35 are set to the position corresponding to the number of stimuli presented to the student. Then, using the Record button (not shown), the generator 10 is connected to the clock inputs of the imaging unit 11 and through the elements 15, to which the unit potential from the output of the inverter 18 is applied, to another input of the register 14. The impulses of the imaging unit 11 through the element 12 and the adder 13 arrive simultaneously at the entrance

the number of units received is read. As soon as their number reaches the value set by switch 17, from its output to the input of the inverter 18, a signal is received that removes a single potential from the inputs of the elements 12 and 15, turns off the driver 11 from the information input of the register 14 and stops feeding clock pulses. 14 unit potentials recorded in the register

served from its outputs to the inputs of one-vibration 19 and 20, the pulses from the outputs of which, going to the corresponding inputs of registers 21, record the unit to the bit to which the output of the corresponding one-shot 19 or 20 is connected. When ready, the learner presses the button The exposure of unit 1 (not shown), and the signal from the output of the generator 9, entering the input of the multivibrator 22, produces a single pulse, the duration of which is equal to the exposure time set in advance. I. pulse from the output of the multivibrator 22, coming through the OR element 24 to the control input of the key 25, provides the supplying voltage from the output of the source 26 to all the inputs of the indicators 40 through the AND 43 element, at the second input of which the unit potential taken from the output of the element AND-NOT 44. At the same time, only those indicators are highlighted.

40 and the numbers on them, which were received

control signals from the registers 21. The subject visually captures both the digits and the placement of the indicators 40, on which these digits are highlighted. Then it reproduces the memorized information corresponding to the highlighted digit on the indicator 40. Pressing the button 39 switches the outputs of the corresponding register 21 from the indicator 40 to the elements AND 32 of the block 7. If this indicator 40 lights up the signal, then the input of one of the elements And 32 comes a single potential. If the stimulus is correctly reproduced, is specified incorrectly, then two units do not go to one of the elements AND 32 simultaneously, and the counter 34 does not count. In this case, after reproducing all the stored information, the indicator 31 does not turn on and the student must repeat the cycle from the beginning or, with permission, repeatedly presses the button "Exposure of unit 1 ,.

the student conducts this stimulus with having fixed the answer, passes through the element using the button 41 from the generator 9 through the corresponding AND 28 to the input (shift) register 27 and the corresponding element AND 32 and the OR element moves the unit to the village. 34 unit is recorded, trig r. The unit potential from the output register 45 is transferred to one state, from par 27 is fed to the input of one-shot 20 If the stimulus or indicator, on which one of the nodes, and the pulse from its output

also arrives at element 29, highlights the banner “Indicate the error of indicator 31, and sets counter 30 to the initial state. After a delay time equal to I-2 s, the pulse from the output of element 29 turns off the indicator 31 and enters the input of the multivibrator 23, which produces a single pulse. This pulse provides a flashing of indicators 40 and

Answer the corresponding trigger 45 is not an Era- 15 digits on them. The learner visually finds out, at the output of the NAND 44 element - nods, and then fixes the indicator 40 to a single potential, which ensures that the error was detected and the voltage potential passed through the digital potential to the error value. If the learner is correct from the key 25 on the indicator 40. The indicator 40 but reproduced the error, then the latter simply indicates the information received by. the counter 30. At the same time, the pulse from the output of the element E 28 receives a response, the corresponding trigger 45 translates the input of the register 27 and moves the unit to the one state by the potential for the next bit, ensuring that the voltage from the output of the AND 32 block, making the introduction of a new error, since it measures the registration and thus ensures the state of one of the registers 21. If the passage of the pulse voltage, then the student 25 incorrectly reproduced the error on the second input one of the element AND-NOT ku, then the cycle can be repeated first or 44. At the time of coincidence, potentially press the button “Exposure of block I and ala from divider 42 with the potential from the output of the trigger 45 at the first input of the element I

43- zero potential, and as a result, at the output of the latter - zero potential, prohibiting the operation of the indicator 40. At the end of the pulse duration from the splitter 42, the frequency at the output of the NAND element

44 - single potential, which is to develop his mistake.
