The imaging unit 3 contains the elements 41 and 42 of the delay switches 43i-434, the encoder 44, the shift register 45.

The device works as follows.

The switches 43 preset the signs, for example, B.ZH, 3, L, which are approximately the same in length and, in accordance with the letters, place the labels on the buttons 37 in the same order.

Turn on the power, press the Start button 38, set the device to the initial state, and the triggers 24 and 25 to the second position (at the second output - 1 unit potential), start-up. torus 1.

The impulse of the first output of the generator 1 is fed to the inputs of the flip-flops 36, ensuring the appearance of zeros at all the outputs, which

5 is applied to the first inputs of the group of block 4, and the input to the distributor 2 causes the appearance at its first output of a logical unit, which is applied to the first of the second inputs

0 block 4, preparing the chain of correct and incorrect answers, and through the switch 43i to the input of the encoder 44, providing a telegraphic sign in the form of a binary formalized number on its outputs.

5 Simultaneously, the pulse from the output of the generator 1 is fed through the element 41 to the input of the register 40, making the transition last. it in the mode of parallel recording, and, having passed through the element 42, - to the input of the register 40,

0 provides parallel writing of the binary number from the outputs of the encoder 44 to the register 40.

With the arrival of pulses from the output of the generator 1 with a frequency of the order of

5 30-40 pulses per second to the input of the register 40 from the output of the latter, the code combination is advanced, which is fed to one input of the key 10. The sound that arrives at the other input of the key 10 oscillates

0, the frequencies from the output of the generator 9 are formed into the sound image of the telegraph sign (Fig. 76), which through the prohibition element 19, on the control input of which the ground potential is applied from the first output of the trigger 24

5 (FIG. 7a), and the element 20 OR is supplied to the electroacoustic transducer 14.

The student, having listened to the telegraph sign (melody), identifies it and presses the corresponding button 37 on the remote control 5, on

0 the nameplate of which identifies the identified letter, for example B, by transferring the corresponding trigger 36 to a single position.

If the trainee incorrectly identified the sign, that is, instead of the button 371, on the nameplate which is marked with the sign B, pressed the button. on the pin of which is indicated by the sign Ж, then at the output of block 4 there is a unit impulse of an incorrect response, which, through element 27, a zero potential is supplied to the control input of the first one

trigger output 24, and the element 29 And will go to the input of the trigger 25, ensuring the appearance of a single potential at its output, and to the input of the countdown of the counter 6.

A single potential from the output of the trigger 25 is fed to the input of the generator 1, turning it off, and to the input of the banner 34, illuminating the Stop warning the trainee (manager) about the impossibility of his training in fading due to insufficient digestion of telegraph signs.

If the student correctly recognizes the sign, then when the button 37 is pressed, the unit potential from the output of the trigger 36 goes to one of the first inputs of block 4, the corresponding potential of which is supplied to the unit potential from the output of the distributor 2. Fig. 7 c), which is fed to the input of the direct counting of the counter 6 and through the input of the switch 22, the control input of which has zero potential from the first output of the trigger 24, is applied to the counting input of the counter 23, fixing the correct answer.

The student, after listening to the melody of the sign,

5 presses the corresponding button 37 on the remote 5.

If the answer is correct at the output of block 4, the Wits impulse is transmitted through element 30 I and switch 22 to the input

0 of the counter 23, fixing the mark presentation, and at the input of the direct count of the counter 6, changing the state of the decoder 7 and performing the switching in the divider 8, increasing the limits of the level change

5 of the next signal, i.e. will increase the amount of fading.

If the answer is incorrect at the output of the unit 4, according to Wits, the pulse that through the element 30 OR and the switch 22 enters the

0 the counting input of the counter 23, fixing the mark presentation, and the input of the counting counter counter 6, changing the state of the decoder 7 and performing the switching in the divider 8, reducing the change limits

Level 5 of the next signal, te will reduce the amount of fading.

At the end of the first stage of training, at the sixth exit of the counter 16, a pulse appears, which throws the trigger 40

0 in a single position, illuminating the banner End on block 13. In this case, the total number of signs presented to the student corresponds to the position of the switch (digit, not shown) on counter 23, multiplied by five (number of cycles), and the number of incorrect answers is indicated counter 31.

If the student interrupts the training until the end of the stage, then presses the button 39 of the console

0 5, throwing the trigger 40 in a single position. A single potential from the output of the trigger 40 is fed to the input of the key 33, highlighting the led 32, corresponding to the number of (processed) cycles,

5 and at the entrance of the banner End

Based on the readings of the counter 31 and the number of cycles worked out, the level of trainability and readiness of the operators to conduct the exchange over the radio links in fading conditions is determined.
