However, this simulator does not allow one to assess the test subject's ability to measure different duration of sound images of the signal, which reduces the quality of selection. The aim of the invention is to improve the accuracy of the device by taking into account the test subject's ability to compare different elementary sound images of different duration, expressed in terms of frequency (transformation factor. The goal is achieved by the fact that 8 devices containing a single pulse shaper sequentially connected operator panel and control unit, a series-connected comparison unit and a display unit and a series-connected first OR element and an electrical conversion A spruce is inserted, a serially connected equalizer pulse generator and a single pulse driver unit whose output is connected to the first input of the first OR element, and a second input to the first output of the control unit, the second input of which is connected to the second input of the first element OR through the single pulse driver , the input of the equal-voltage pulse shaper is connected to the first output of the control unit, the first input of the comparator block is connected to the output of the equal-voltage pulse shaper, and the second input is to the second output of the operator’s console, the control unit contains the first group of triggers and the element I, the output of which is the first output of the block, the inputs of the first group are the input and the second output of one of the first group triggers the second output of the block, the equalizer pulse shaper contains a series-connected generator, the second group of triggers, a group of inverters and the first group of elements AND, the second inputs of which are connected to the outputs the second group of triggers, the third inputs of which are connected to the driver input, and the outputs are the output of the driver, the comparison unit contains the third group of triggers sequentially connected, the second group of AND elements and the second OR element whose output is the output of the block, the trigger inputs of the third group are connected with the first input of the block, and the second inputs of the elementosis And the second group are connected to the second input of the block. 4 In FIG. 1 shows a block diagram of the device; FIG. 2 is a diagram of a shaper of equal power pulses; FIG. 3 is a block diagram of the comparison. The device for professional selection of radio telegraphists contains a series-connected operator console 1, a control unit 2, a single pulse shaper 3, a multiple-input element OR k and an electroacoustic converter 5 connected in series to a uniform RF pulse shaper, the input of which is connected to the control unit 2, the comparison unit 7, the other inputs of which are connected to the outputs of the generator 1's console, and the 8-indication unit, which includes indicators 9 (light bulbs of different colors), as well as the block of 10 formers dinochnyh pulses, some inputs of which are connected to the second output of the control unit 2, the other inputs - with an output of 6, and outputs - to the inputs of multi-input OR element. The control unit 2 consists of the flip-flops 11 and 12 and the element And 13. The block 10 consists of the formers 1 of single pulses. The display unit 8 has a series-connected counter 15 (correct answers) and a decoder 16. Shaper 6 contains a generator 1 / (uiyMa), triggers (Schmitt) 18, which are supplied with reference voltages U O Vg, inverters 19 and I elements 20. A block 7 comparisons contains triggers 21, elements AND 22, and a multi-input element OR 23. The device operates as follows. When the power is turned on, the triggers 11 and 12, the counter 15, the decoder 16 and the triggers 21 are reset. In accordance with the test method, the applicant presses the Signal (not shown) button on console 1, listens for and remembers the duration of the first control signal (impedance), which it should take as a reference (elementary) for comparison with the subsequent signal. Then, again, presses the same button and listens to the duration of the second signal. By comparing, commensurate with each other, the duration of both transmitted signals, the subject determines how many times the duration of the first control signal is longer (shorter) than the duration of the second signal, i.e. calculates the transformation ratio by duration. Starting from a series of buttons with numerical symbols of transformation ratios (not shown) located in the panel 1 of the subject, presses the button that corresponds to the transformation ratio calculated by him. In this device, the transformation ratio can have values from 1 to 10. When you press the Signal button on the remote control 1, a pulse from its output transforms the initial state unit 2 to the first, i.e. the impulse, acting on the counting input trigger 11, causes the appearance at its single impulse output. This impulse triggers a sweeper 3, which forms the first pilot signal. The control signal through the element OR 4 is supplied to the electro-acoustic transducer 5, which reproduces the audible image of this signal. The subject listens to the sound image of the signal and remembers its duration. Then repeatedly presses the Signal button. A pulse from the output of the console 1 transfers the block 2 from the first state to the second, i.e., a pulse coming from the console simultaneously acts on the counting input of the trigger 11 and the single input of the trigger 12 and causes the appearance at the zero output of the trigger 11 and the single output three1 - Gera 12 pulses that arrive at the first and second inputs of the element 13. From the output of the element 13, the pulse arrives at the first inputs of the block 10 of the formers 14 of a single pulse and to the interrogator input of the imager 6. Each of the formers 14 generates a single pulse only with the post When the pulse arrives from the output of the AND 13 unit 2 on the interrogation input of the AND 20 elements, the condition: V., where V j is the voltage amplitude at the output of the generator 17. In this case , i the first Schmitt triggers 18 will be triggered, the signals from the outputs of which are sent to i of the corresponding elements And 20, but from neither the first i - 1 are closed on the second input by the corresponding signals from the outputs of the inverters 19. As a result, at the time of polling the signal only appears at the output of the i-th element And 20. At ten op voltages V (i.e. used ten trig (Schmitt's ger), - the probability of a signal appearing at the I - m output P 0.1. The outputs of the imaging unit 6 are also connected to the inputs of the comparison unit 7. In this case, the impulse received from the 1st output of the imaging unit 6 to the i -th and the imaging unit 14 of the block 10, is also a post. Pit in the i-th PS-flip-flop 21 of block 7 of the comparison. In this case, the pulse received from the i-ro output of the driver 6 to the i-th driver 14 of the block 10 will also go to the i-th trigger 21 of the comparison block 7, i.e. corresponding to the number of the connected driver 14 of single pulses. From the output of block 10, a signal of a certain duration through the element OR 4 will go to the electro-acoustic transducer 5 and presented in the form of a sound image to the subject. As a result of comparison of the control and subsequent signals, the subject determines how many times the duration of the second signal is longer (shorter) than the first, t, e. Calculates the transformation ratio and presses 1 button on the remote control that corresponds to this transformation ratio. If the test responded correctly, ITO at the output of the element AND 22 of the comparison unit 7 will receive a pulse, which through the element OR 23 will go to the input of the counter 15 of the display unit 8. If the subject answered incorrectly, nothing will be recorded in counter 15. By pressing any of the buttons of the transformation ratios, the triggers 11,12 and 21 are reset. The subject proceeds to the next (second) stage. The entire verification cycle consists of ten stages (repeats), in each of which the second signals are randomly displayed (with a probability of P 0.1). At each stage, the scheme works in the same way as described. At the end of the cycle (after the tenth stage) the results of responses with counters are. 15 is read in parallel code into decoder 16, from which output the test result is displayed
