The operator presses the Start button 39, starting the driver in block 14. A single pulse from its output (FIG. 4, d) through the OR element 20 of block 4 enters the input of the distributor 21, sets it to the first position, flashing on the indicator of the block 13 1 (first cycle) and submitting to the headphones 19 are small in terms of (sound intensity) noise (Fig. 4, d).

Clock pulses from the output of the generator 45 to the input of C {register 44, the sign written in it is extended (Fig. 4e).

When the first element of the sign (unit) appears at the input of the element OR-HE 46, a zero potential appears at its output (Fig. 4a), causing the appearance of the short pulse at the output of the former 7 (due to the falling front), which is fixed the counter 6, and acting on the control input of the key 16, stops the flow of interference to the headphones 19 Q (Fig. 4e). The code combination of the character from the first output of the imaging unit 1 is also fed to the first (informational) input of the register 24 of block 5, the record. When a key is pressed, an impulse appears at the output of the input of the OR element 54 and the corresponding input of the encoder 51, providing at its output Forming a Morse code sign in the form of a double-sided combination, in which the point corresponds to 1, a dash is 111, and the pause between the elements of the sign — Pulse from the output of the OR 54 element goes to the input of the delay element 55 and to the input V of the register 52; in paral mode write. The delayed pulse from the output of element 55 enters the input C of the register 52, ensuring parallel recording of the binary combination from the output 35 of the encoder 51 to the register 52. The clock pulses from the output of the generator 53 received at the input C, the register 52, advance the sign recorded in him.

When the key is pressed, an impulse appears at its output, which enters the input of the OR 54 element and the corresponding input of the encoder 51, providing at its output a formation of a Morse code sign in the form of a two-key combination in which the dot corresponds to 1, the dash - 111, and the pause between the elements of the sign — Pulse from the output of the OR element 54 is fed to the input of the delay element 55 and to the input V of the register 52, translating it into parallel recording mode. The delayed pulse from the output of element 55 is fed to the input C of the register 52, ensuring parallel recording of the binary combination from the output of the encoder 51 to the register 52. The clock pulses from the output of the generator 53 received at the input C, the register 52, extend the sign recorded in him When a first element appears at the input of the element OR-NOT 56, a zero potential appears at its output (Fig. 4, g), which is applied to the control input

and to the input of the imaging unit 8. The leading edge of a single potential (pulse) causes the appearance at the output of the imaging unit 8 of an impinge (Fig. 4, k), which is applied to the input of the delay element 10 and to the input of the generator 27, to start its "Pulses from the generator output 27 (Fig. 4, l), entering through the elements OR 28 and 29 at the inputs of the registers 24 and 25, respectively, reads the information from their outputs in the adder 26,

If the operator correctly reproduced the sign, then the code combinations recorded in registers 24 and 25 are identical, there is no signal (pulse) at the output of the adder 26.

If the operator incorrectly reproduces the sign, then the faa output of the adder 26 appears pulse (pulses), which through the element OR 30 enters the input of the counter 6 and sets it to the initial state. The pulse held by the element 10 (FIG. 4, m) is fed to the input of the imaging unit 1 and provides the operator with the next character.

If the operator recognizes and reproduces the correct error of ten characters, then at the output of counter 6, an impulse (overflow) appears, which enters the second input of the trigger 31 and transfers it. The zero potential from the first output of the trigger 31 turns off the generator 32, stopping the supply of time marks, and the single potential from the second output turns on the indicator 35, highlighting at the last adaptation time in the first cycle

At the same time the pulse from the output of the counter 6 through the element OR 20 is fed to the input of the distributor 21 and translates it into the next, second position. In the display of block 13, 2 is lit (second cycle). Interference from the output of the generator 3 through the key 22 and the limiting element 23g (with less resistance than 23) is fed to the information input of the key 16.

The following signs are presented to the operator with a higher level (sound intensity) interference between them.

By the length of adaptation in each cycle, the possibilities of the operator to conduct radio reception in real conditions are judged.

The use of the invention in operator training devices will increase the efficiency of the simulator by developing the skill of maintaining radio reception under the influence of residual and reverse interference due to a step change in the sound power of the interference when the operator’s hearing organ adapts, defined by a series of correctly identified and reproduced Morse code, which allows define
