The second control inputs are connected to the outputs according to the 11 and the second 12 elements, and the multiplexer 9 is connected to the first input of the display unit 17, the other two inputs of which are separately connected to the outputs of the first simulator 10 "

The device works in the following way.

In the software control unit 13, the coordinates of the beginning of t and the end of t6 (Fig. 1a) of the section are specified, taking into account the delay of the control signal in the filtering unit 8, by the delay time Ј- (Fig. 1a).

The digit 15 establishes the number f ″, which is added in the adder 14 to the coordinates of the beginning f, and the end tg of the section (FIG. Ia) with m, so that the control signal boundary of the second unit 7 selects the corresponding

Vova the zone of change of the parameter f from f to f 3 (Fig. 1a).

When playing a magnetogram in the presence of errors in the amplitude of the parameter f at the time of dormancy from to t a, and from. t-f to tg (Fig. 1a) at the output of the filtering unit 8 is generated

The O control signal (Fig. 16), which is fed to the second input of the 2 key block, opens it, and the measurement information (Fig. 1g) from t5 to tr from the 1 playback block (phi 2) is

5 is generated via analog-digital converter 3 to processing line 4. At the same time, the control signal (Fig. 16) is fed to the first driver 10, the first output of which is allocated

0 positive signal front (Fig. 1c), a. at the second output, there is a negative front of the signal (Fig. 1d), corresponding to the coordinates of the beginning of t g- and the end t7 of the input area (Fig. 1g). Similarly, the control signal from the output

the second block of site selection 7 highlights the positive (Fig. 1e) and negative (Fig. 1e) fronts of the signal, indicating respectively given

The value of the coordinate of the beginning t and the end t of the plot (Fig. 1a). Under the action of interference at the time from t to t3 (Fig. 1a) e causing the coordinate of the beginning of the plot to shift to t5 (Fig. 16), the pulses (Figo 1b, d) from the first outputs of the formers 10 and 16 НЈ inputs the first element And 11 do not match in time. At the first control input multiplex

0, the voltage 9 is supplied with the voltage O, at the second control input of which the pressure O also acts, since the pulses at the input of the second element I 12 are absent. Combinations About - About

45 at the control inputs of the multiplexer 9 corresponds to the first open swing. The code of the number of the beginning of the input area from the second output of the converter 5 of the serial code to the parallel one

JQ enters the display unit 17. By the pulse (Fig. 1c) from the first output of the first shaper 10, the code of the number of the beginning of the portion f (Fig. 1a) is entered into the display unit 17 and displayed on the indicator screen. Under the action

interference at time from t to tg (fi. 1a), which does not lead to a change in time of a given value of the coordinate t7 of the end of the section, pulses

(Fig, 1g, e) from the second outputs of the formers 10 and 16 coincide in time. Voltage 1 from the output of the second element And 12 goes to the second control input of the multiplexer 9, at the first control input of which at this time the voltage O acts, since there are no pulses at the input of the first circuit And 11. The combinations of the CM at the control inputs of the multiplexer 9 correspond to the third open channel. Code the number of the end of the plot with the third output of the adder 14 is supplied to the block 17 of the display. The pulse (Fig. 1d) from the second output of the first generator 10, the code of the number of the end of a given segment fg (Fig. 1a) is entered into the display unit 17 and displayed on the indicator screen.

Under the action of interference at the end of the section leading to the disparity of the boundary of the section to the specified value, the first channel of the multiplexer 9 is opened. A pulse (Fig. 1d) from the second output 3 of the first shaper 10 code is stored in the display unit 17 and displayed on the indicator screen.

Under the action of interference at the beginning of the section, which does not lead to a change in its coordinate, the second channel of the multiplexer 9 opens. A pulse (Fig. 1c) from the first output of the first driver 10 (Fig. 2) is entered into the display unit 17 and displayed on the display screen.
