In addition, the signal duration conversion unit has a trigger, an OR logic element, AND logic elements and a time delay element, with one of the outputs of the beautiful prohibition block connected to the inputs of all the time delay elements and one of the trigger inputs, the other input of which is connected to the output the logical element OR, the outputs of the elements of the time delay through one of the inputs of the logical elements And pa connected to the inputs of the logical element YUSH, and the second

Claims (1)

In the first mode, the student listens to a single impulse. The mode is set by a switch (not shown in the diagram) of the operation mode selection unit 2. Block 2 generates a signal that is fed to one input of logic element 6. The learner presses key 4, and a generator of 5 single pulses is started, which generates a pulse of a certain duration S. This impulse goes to the second input of the Ibis output logic element through the logic circuit OR 9 - to the input of the electroacoustic converter 8. The trainee listens to the sound image of the pulse and goes to the second mode, in which he must reproduce using the key 4 and the pulse duration of PI in accordance with methods of shoe; e sh. The number n 1, 2, 3 ... is set by /; it is found in block 3 of the conversion scale setting. The student presses the key 4, maintaining the duration of pressing nt. The signal from the key 4 simultaneously enters the trigger input of the generator 5 single pulses and to the input of the imaging unit 15G pulses. From the output of the imaging unit 11 pulses, the signal is fed to the ODI input of the logic element I 19 and to the information input of the logic element 10 of the prohibition. In the second mode of operation, the signal from the mode selection unit 2 is fed only to the second input of the logic element I 7 and to the start-up input of the generator 18 timestamps. As a result, there is no signal at the output of the logic element I 6, and since it is connected to the inhibit input of the prohibition logic element 10, the signal from the driver 11 pulses passes through the prohibition logic element 10 and the logic circuit OR 9 to the electroacoustic converter 8. The student has hearing control the transformed impulse it forms. Simultaneously with the key 4 being pressed, a generator of 5 single pulses is started, the pulse from whose output through the logic element 7 arrives at the input of the signal duration conversion unit 12. The leading edge of this pulse, acting on one of the inputs of the trigger 18, transfers the latter to the state at which the signal appears at the first input of the logical element AND 17. Since in the second mode the time stamp generator 18 is turned on, then the second inputs of the logic Elements And 17 and 19 receive pulses with a frequency of timestamps. At the outputs of logic gates And 17 and 19, the same signals are formed - time stamps, which are fed to the input of the comparison circuit 20. The comparison circuit is made on logic elements And 24, 25 and 26, as well as inverters 22 and 23 in such a way that with equal signals at the outputs of logic elements And 17 and 19 (and consequently at the input of the comparison circuit) from the output of logic element And 25 the signal is not removed and nothing is entered in registration block 21. A student can form an impulse whose duration is less than nJ. In this case, the signal from the pulse driver 11 is terminated earlier than the control signal from the output of the signal duration conversion unit 12. At the output of the logical element AND 19 there is no signal, and from the output of the logical element 17 and 17, the comparison circuit 20 still receives timestamps. In this case, the comparison circuit 20 skips them to the registration unit 21. The duration of the converted pilot signal is specified on block 3 of the conversion scale setting. At the same time, the corresponding logile element AND 15 is connected, which transmits a pulse of fixed duration from the output of the element 14 to a time delay to the input of the logical element OR 16. From the output of the logical element OR 16 the pulse, acting on one of the inputs of the trigger 13, bring it to the state , in which the input signal And 17 does not receive a signal from the trigger output, as a result, nothing is received at the input of the comparison circuit 20 and information is not entered into the registration unit 21. In this way, a learner using the registration block 21 can determine the magnitude of the error made by him, since the number of timestamps recorded in block 21 corresponds to the time difference between the control signal and the signal transformed by the student. When a trainee generates a pulse with a duration longer than pT, the simulator works similarly. The only difference is that the signal from the output of the flip-flop 13 stops first, and the comparison circuit 20 provides the time stamps only through the AND gate 19. The registration unit 21 also records the number of time marks proportional to the error allowed by o6y4aeNnjM. The use of the invention makes it possible to improve the quality of training by taking into account additional human functions associated with its ability to transform elementary signals while at the same time controlling their reproduction.
