Description

ti 5, first counter 6, block 7, second counter 8, register 9, elements 10, adder II, third counter 12, pulse generator 13, second photoelectric converter unit 3OBaffH3 14, made in the form of matrices, php HCMHbix elements, coordinator shaping unit 15 signals containing ySejflbljablfe with the initial abscissa of the coordinate grid 16 and the selection node of the ordinate of the base line 17. The device works as follows, Using an optical system (not shown) on the receiving cathode-ray tube 2 of block 1, an image with n is projected about, that the shrinkage of the diagram. Unit 3 generates sawtooth pulses that feed the electrical system to the bias system of the electron beam of the VOY tube 2, and which triggers the impulse at the beginning of the scan, and supplies the counter generator to the pulse generator 13 and to the input of the first counter 6, which is a loop counter. The 6th unit is increased by one and the number obtained in it determines the number of the curve, the ordinate of which is found in a given sweep cycle. TotM impulse block 3З1пусЖЕееШрет8 | The plot of owls 13, from which high-frequency pulses are output to the input of the second counter 8, is indicated by an ordinate counter. With the help of an additional optical system (not shown), the image of the section of the diagram with the baseline is projected onto block 14, with kbtoporo the signal is fed to the input of the node of the orthognies of the baseline 17 and to the input of the selection node of the initial beam. -. j:: -.

From the output of the selection node op; the cords of the base line 17, the deviation value, is fed to the first inputs of the adder 11. To the second inputs of which the ordinate value is fed from the output of the counter 8 ordinates. From the output node of the selection of the initial abscissa of the coordinate grid 16, the KEYNESS is fed to the second address inputs of block 5. Before the processing of information begins, block 5 records 1 to all addresses corresponding to the measured ones for reading the Chart Points, i.e., free from the coordinate grid. At the rest of the addresses, the entries are zero. When a signal is received at the output of the video signal generator 4, it is transmitted to the control module of the accumulator 11, as a result of which the output of the adder 11 appears exactly a5i,., I, .ra; -; ;. - -jjoEfcsB.tfenUe about edyyats, which is fed to the first address inputs of block 5. At the address inputs of block 5, an address is formed consisting of the exact value of the ordinate and the deviation of the initial grid grid. The video signal coming from block 4 permits reading from block 5. At the initial moment of the Uretia, the 12 curve curves are set to zero. 1, from the 14V block. If at this point the readout is allowed, then the output of block 5 will be the signal that arrives at the input of the counter 12 curves, increasing its content by one, and the input of the elements AND 10, allowing the value of the ordinate from the adder 11 to the inputs of the register 9. The comparison unit 7 compares the values of the counter 12 of the curves and Meters withstand 6 cycles. In the case of the scrapping of these quantities, the signal from the output of the block and the comparison arrives at the control input of register 9, permitting; Writing the value of ordinates to it. In case if the counters are not given at this point, W1GR1N1 is not {5this allowed, then the value of the counter 8 krebB1) is increasing, and the element 10 does not miss in4) Ormation on the input of the register 9 Zey allowed to significantly increase the device. .
