The output of the clock pulses 36 of the block 33 is connected to the second input 21 of the clock pulses of the block 19 and to the input 40 of the clock pulses of the match block 39. The output of the dynamic memory unit 12 is connected to the first input 17 of the comparator 16, the output of KOTOfipro is connected to the input 41 of the print resolution of the block 39. Pulse output 26 of the driver 23 is connected to pulse inputs 29 and 37 of the driver 28 and block 33. Code output 27 of the driver 23 connected to code input 43 of graphic recorder 42, pulse output 32 of driver 28 is connected to pulse input 38 of block 33. Code exit 31 of driver 28 is connected to the second input of block 16. Output 39 is connected to input 44 of recorder 4-2. In the initial state, the addresses of the addresses 23 and 28 are common, the key 9 and the switching unit 19 are closed. The device works as follows. The measurement signal from input block 1 goes to the character calculation block (tick 2j where various signal characteristics — correlation, spectral and probabilistic) are obtained. All characteristics are computed and output "in parallel". From the outputs 3 of block 2, the characteristics in the form of analog voltages are fed to the switch 4, and from here from output 5 to the analog .. -diffraction converter 8. At the output of the ADC, thus, a frame (sequence of codes) is formed; Each point of the characteristic takes a definite place relative to the pulse of the beginning of the frame (marker), and its intensity is characterized by some code. The frames are repeated cyclically in accordance with the polling period of the switch 4. Each period is divided into two stages,. . At the first stage, data is entered into the dynamic memory unit 12. For this, the control and synchronization unit 33 arrives at the input 34 of the first polling of the interrogation of the switch 4. (marker see Fig. 2a) generates a potential (F1n, 2b), which opens the key 9 and permits the passage of cimxpoHNJfulses of filling from the output of 6 com mu-. ator 4 through the switch unit 19 to the address address distributor 23. As a result, the codes from the ADC 8 pass through the key 9 to the block 12, and their place in the block

the memory is determined by a clock signal at the input 15 of the switching unit 19. The sync pulses arriving at the input 24 of the forker of the address of point 23, (FIG. 2d), are counted. Once

the fn-thru sync of myc filled-in ™ | NII comes, which corresponds to the last point of the x; characteristics, the filling of the block of dynamic memory 12 stops and the whole device goes to the stage of data output on the schedule. For this, the control and synchronization unit 33, according to the signal from the output 26 of the address generator of the 2Q point, coincides with the last, TP point of the characteristic polling, closes the key 9 with its control signal from the output 35, permits the issuance of sync pulses data from its output 36 through the switching unit 19 to the input 24 of the address address generator 23 instead of the sync pulses, as well as applying the sync pulses from the output 36 to the coincidence block. Day 39 (fig.2d). The clock pulses of the output (clock cycles) are fed to the input 25 of the driver of the address of point 23, and the codes from this form. The peacemaker is fed to code input 4.3 of registrar 42. These clock codes alternate but prepare for printing the ordinates of the graph of each line (see Fig. 3), but in order for the dot to be printed, a clock pulse must be sent to the graphic recorder produced by the unit compared to “neither 16 codes. Printing is done line by line, i.e. first, the points of one line (verticals on fn.2) are sorted out 5 then the other and so on. The number of lines is determined by the number of gradations along the axis of ordinates of the characteristic.

In order to ensure the printing of points synchronously with the codes of the address generator of the points 23, the control and synchronization unit 33 provides for the cyclical supply of character codes. From block 12 to input 17 of block 16, input 18 of block 16 compares the RING address of the string from the driver 2 8, which reads the number of lines (revolutions in the block of dynamic memory — see Fig. 2e). The codes of the form .. body 28 correspond to the line number and, at the same time, a certain gradation of the characteristic along its axis of ordinates. If at some point defined by line i and point J in FIG. 3, the characteristic code is equal to the code of the address line 28 address generator, then the comparison unit 16 generates a pulse (Fig. 2g), which opens input a matching block .39 at input 41 and enables the sync pulse from output 36 of control unit 33. pass to input

44 registrar 42, providing point printing. As ToniiKO and the block of dynamic memory will be made P turns, i.e., all gradations of the characteristics will be exhausted

all the points of the characteristic are printed on the abscissa axis (all lines), the output of the address line 28 is output from the output 32 of the scrolling and synchronization block 33 to an impulse (FIG. 2i), along which

In addition, the control unit 33 restores the entire device to its original state. With the arrival of the next marker from switch 4, the operation of the circuit is repeated.

Thus, the same type of statistics

The char- acteristics calculated on the segments are precisely located one under the surface, which sharply increases the fineness and efficiency of further processing.
