The apparatus operates as follows. When the power is turned on, the register of counters 28-31, 13 and reversible counters 37-40 are poured into the initial state. After appropriate instruction, the subject presses the Start button 41. The impulse from the output of the button 41 enters the second R -to-flip-flop 18, sets the latter to the zero state, to the first input of the generator 1, turns it on and provides pulses from the output of the generator 1 to the second input of the circuit 8 And (1000 Hz) and input of node 2 (500 Hz). At the outputs of dividers 22-27, which are connected in series, but each divider has its own output, there appear pulses, the duration of which is equal to 2.4,8,16,32 and 96 de facto (figa). These pulses arrive at the inputs of counters 28-31, respectively, from the outputs of dividers 22-25, to the first inputs of circuits 36 and 8, respectively, with the output of dividers 26 and 27. Counters 28-31 have an effective number of 12, 6, 3 and 2, respectively, i.e., after the arrival of the corresponding impulse to the counter, which is higher than the permissible value, the output of the pulse is at the output, and the counters start counting from the beginning (fig.2b). Overflow pulses from the outputs of the counters 28-30 go directly to the inputs of the AND 32-34 circuits, respectively, and from the output of the counter 31 through the delay element 10, the output of which is also connected to the synchronizing input of the sensor 11. The output of the divider 26 is connected directly to the first input of the circuit And 36, and the divider 27 - to the first input of the circuit 8. From the output of the divider 27 to the first input of the circuit AND 8, the pulses are also received for a duration of 96 ms. Since at the third input of the AND 8 circuit there is a single potential from the output of the inverter 7, then the arrival of the second input of the pulses from reHepaiTopa 1 is passed to the EAP 9. The examinee listens to ten audio signals of 1000 Hz and stores them (Fig. 2d). After passing a ten pulse at the output of the counter 13, a pulse of overflow occurs, which goes to the first input of the circuit 14, through the delay element 15 to the information input of the prohibition element 17 and through the delay elements 15 and 16 to the inputs of the initial state counters 37-40 (delay elements 15 and 16 ensure clear operation of trigger 18 and prohibition element 17). If there is at least one of the outputs of the counters 37-40 of the single potential, the overflow pulse from the output of the counter 13 will go through the AND 14 circuit to the first 5 input of the trigger 18 and transfer it to the single state. But since there is no information in the counters 37-40 (they are in the initial state), the overflow pulse to the first input of the trigger 18 will not pass (the second input of the AND 14 circuit has a zero potential), the trigger will not change its state. At the output of the prohibition element 17, the signal turns on (a somewhat delayed overflow pulse), which will ensure the appearance at the first output, a register 12 of a positive potential. This potential, acting on the second input of the AND 36 circuit, the first input of which receives pulses from the output of divider 26 (32 ms duration), will ensure the passage of the latter to the input of the inverter 6. The zero potential from the output of the inverter 6 through the OR circuit 5 will enter the input of the inverter 7 A single potential from its output, applied to the third input of the circuit And 8, will ensure the passage of the audio frequency from the output of the generator 1 in the EAP 9. Termination of the pulse from the output of the circuit 36 will cause the appearance of a zero potential at the output of the inverter 7, and the passage of the start frequency in EAP 9 will stop. A B. pulse with a duration of 96 ms will not form a time interval with a duration of 32 ms (FIG. 2d). If the test clearly distinguishes the time interval, then it counts the number of signals at intervals, reports to the manager and proceeds to the first cycle. If the subject doesn’t distinguish between time intervals, he reports to the supervisor and is not allowed to be tested. After ten signals at the output of the counter 13, the overflow pulse will flow, which will transfer the positive potential from the first output of the register 12 to the second, i.e. will send it to the second input of the circuit AND 33. The first cycle of the ten signals will be presented to the subject. In each presented signal, the subject must determine the presence or absence of a time interval. From the output of the AND 35 circuit, a pulse with a duration of 16 ms, delayed by element 10 for the duration of the pulse, will go to the summing input of counter 37 and to the input of the AND circuit 5, if the output of sensor 1 is logical 1. This pulse goes through AND 5 circuit the input of the inverter 7, causing at its output the appearance of a logical O, which, acting on the third input of the circuit 8, will ensure the occurrence of a time interval in the signal (Fig. 2c). This interval will occur randomly in a 96 ms signal. If the subject, listening through EAP 9, a tone frequency signal of 1000 Hz, distinguishes a time interval in it, then presses button 42 (of the corresponding cycle); if it does not, it does not perform any actions. With the correct answer. (There is an interval and the subject distinguishes it) the pulse from the output of button 42 goes to the subtracting input of counter 37, ensuring at its output a zero loss. If there is no interval in the signal, the test subject does not press the button 42 and the zero potential at the output of the counter 37 is zero. If the subject, although 0y in one signal, does not have a time interval, then the output potential of the OR circuit 21 connected to the output of the reversible counter 37 is equal to one potential. When the overflow pulse arrives from the output and the counter 13 (at the end of the first cycle), the last will pass through the first input of the And 14 circuit element (since the unit P input of the counter 37 is applied to the second input of the And 14 circuit) to the first S input of the trigger 18 and will transfer the latter to the unit state i. The signal from the output of the delay element 15, which has arrived at the information input of the prohibition element 17, will not pass to the control input of the register 12, since the unit potential enters the inhibitory input of it from the trigger. The same potential will go to the second input of the generator 1 and turn it off. A pulse from output 538 and delay element 16 will return counter 37 to its original position. At the same time, indicator 46 is lit, indicating that the subject was approved in the first cycle. The manager decides to terminate the test (or, if necessary, repeat). If there is no time interval in the signal, and the subject presses the button 42, then the wrong answer will also be recorded, i.e. at the output of the counter 37 in vits unit potential. After the ten signals of the cycle have passed, the generator 1 turns off and the indicator 46 lights up. If the subject identified all the time intervals presented to him, then the potential 37 at the output of the counter is zero, the trigger 18 remains in the same (zero) position, the overflow pulse from the counter output 13 through the delay element 15 and the prohibition element 17 will pass to the control input of the register 12 and provide a positive potential at the third output of the register 12, i.e. The subject will be presented with a second cycle of ten signals. In the second cycle, the pulses come from the output of the AND 34 circuit, while the counter 38, button 43, indicator 47 is working. In the third cycle, the pulses come from the output of the And 33 circuit and the counter 39, button 44, indicator 48 work. In the fourth cycle, the pulses come from the output The circuits And 32 and the counter 40, Button 45, indicator 49 operate, while the time interval (pulse) decreases from the first to the fourth cycle from 16 to 2 ms. The operation of units and elements of the device in all four cycles is similar to the work in the first cycle. If the subject in all four cycles gave the correct answers, which corresponds to the highest estimate, indicators 46-49 are hot, a 96 ms signal with a frequency of 1000 Hz is sent to the input of the electroacoustic converter 9. The use of the proposed invention in devices for the pro-selection of radio telegraphs allows one to determine the subject's ability to perceive temporary signals. This gives opportunity)
