When the power is turned on, the counters are reset.

313

5, 24 and 29, distributors 8 and 38, triggers 3 and 27 are set to zero, generators 1 and 33 are turned on, indicators 44 are highlighted.

When the subjects are ready, the head presses the Start button of the imaging unit 33. The pulse from its output through element 7 enters the input of the distributor 8 and transfers the latter to the first position, ensuring the supply of the unit potential from this output to the first input of the sixth element I of block 10, to the second the input of which receives pulses from the sixth output of divider 2, the duration of the pulses and the pause between them is 120 ms. These pulses (Fig. 3a) pass through the element 11 to the inputs of the element 25 and the counter 24. As from the output of the trigger 27, a zero potential (Fig. 3B) is applied to the inhibitory input of the element 25, the pulse from the output of the latter goes to one input element 31 (fig.Sv) At the same time, pulses from the output of element 1 are fed to the input of the inverter 12. A zero potential from the output of the inverter 12 (FIG. 3) attached to the input of element 30 does not change the trigger connection 29 ( Fig. Rear). A pause following the pulse provides a single potential at the output of the inverter 2, which passes through the element 30 (if a single potential is supplied to the other input from the output of the trigger 28, Fig. Ze), goes to the information input of the element 26, to the inhibiting input which gives a zero potential from the output of the trigger 27, translates the trigger 29 into a single state and delivers a positive potential (Fig. A) to the other input of the element 31. When the second pulse arrives from the output of the I1, the latter also passes to the element 31 ( Fig. Sv). At the output of element 31, a continuous signal appears - a single pulse (Fig. ЗЖ), which is fed to the input of the distributor and to the control input of the key 34, to the information input of which the tone frequency is supplied from the output of the generator 33. Sound image - a signal through headphones 35, is submitted by

 persecuted

A pause following the second impulse translates trigger 29 to the zero position (Fig. A).

The third pulse arriving at the input of the counter 24 causes the appearance of an overflow pulse at its output, which, at the input of the trigger 27, changes its state by applying the unit potential (Fig. 3B) to the inhibiting inputs of elements 25 and 26, pause between pulses. The state of the trigger 28 does not change (Fig. 3). At the same time, the overflow pulse is fed to the input of the element 32, the delay time of which is 1 second, and the first input of the trigger 3, the last transfer to one state. A single potential, podanny from the output of the trigger 3 to the input of the imaging device 4, provides the output at the output of the last short pulse (FIG. CZ) which enters the counter 5, fixing the supply of the first cycle of the signal, and through element 18 to the input of the register entry 22, writing unit for the first time, to the input of the driver 21, by running the last one. The sync pulses from the output of the former 21, the frequency of which is 1 MHz, are fed to the shift (first) input of the register 22. The unit recorded in the first digit of the register 22, with a clock frequency, is fed sequentially to the information inputs of the elements 39 and 40.

By testing, after listening to a signal, it consists of one or two tone parcels. If the Test Proves that the listening signal is one package, i.e. he distinguished him correctly, then he presses button 36. The pulse from the output of button 36 goes to one input of element 39 and another potential is applied to the other input through element 41 from the output of distributor 38.

If the Test produces a response within 1 second after presenting the sound image of a signal, then when a unit from register 22 outputs to the third (informational) input of element 39, an output of the element OR 42 is impulse, which enters the input of the corresponding node 17 and captures correct answer.

If the Test in this case presses the button 37, i.e. incorrectly distinguishing the signal, the pulse does not appear on the input of element 42, since there is no unit potential on the second input element 40. When for

If the answer is kept (more than I s), a single potential is not supplied to the third input of element 39. Incorrect and delayed responses are not recorded.

After the delay time of element 32 (1 s) expires, the pulse from the output of the latter (FIG. 3) enters the trigger 27 and transfers it to the zero position, preparing the circuits for presenting the next signal, to the trigger 3, setting it to the zero position through element 20 - to the input of the generator, pa 21, turning off the supply of clock pulses, and to the input of register 22, as well as to the fourth inputs of the nodes 16 and the inputs of the distributor 38, setting them to their initial state. A single potential from the output of the trigger 27 changes the state of the trigger 28 (Fig. Ze), a zero potential appears at its output, which prevents pulses from the output of the inverter 12 to the input of the trigger 29.

The next two pulses from the output of the element 11 through the elements 25 and 31 (Fig. Зж) are fed to the input of the key 34 and the subject is presented with a sound signal from two pieces. Consequently, at the output of block 13, signals consisting of one or two sounders appear (the sequence of presentation depends on the state of the trigger 28).

After ten signals

the device goes to the second cycle. At the output of the counter 5, an overflow pulse appears, which enters the input of element 6 and through element 7 - to the input of the distributor 8, ensuring the supply of a single potential from its output to the first input of the fifth element I. Pulses from the output of the divider 2 with a duration of 100 ms are received at the input of element 1 ,. and the pulse from the output of the delay element 6 returns the counter 5 to the initial state. At the same time, the pulse from the output of element 6 through element 18 enters the input of register 22 and records the unit for the first bit, to the input of generator 21 and switches it on to the input of element 19, the delay time of which exceeds the time of one bypass of register 22. recorded in the register 22, with a clock frequency is fed alternately to the second inputs of the elements 43.

If the subject answers correctly to all ten signals of the first cycle, then from the output of the first decade of the counter 49 to the input of the First element 43 a single potential is applied; When a unit appears at the second input of the element 43, a pulse appears at its output, which is fed to the input of the corresponding indicator 44 and turns off the last one.

The pulse from the output of the element 19 through the element 20 enters the input of the generator 21, turning it off, and to the input of the register 29, setting the latter to the initial state. The subject is presented with a second cycle signal to distinguish.

Then the device proceeds to the third, fourth, fifth, and sixth cycles with a pulse duration of 80.60.40 and 20 ms, respectively. In this case, the elements of the device work as described. At the end of the sixth cycle, the 9 test indicator lights up.

The correct answers recorded by indicators 44 and counters 49, in accordance with the developed methodology, determine the degree of suitability of the subjects for radio telegrapher training.

The use of the invention in devices for professional selection allows to increase their speed (throughput) and accuracy of the assessment of the professional suitability of radio telegraphers by making it possible to determine the individual skills of each subject while checking a group of subjects under the same conditions by detecting each subject. the threshold time for identifying intermittent tones. This reduces the inspection time, improves the quality of selection for Thu prevent learning people do not distinguish or differentiate between hard interval of discreteness.
