The invention relates to 0fH.f VYCHISYAEI tion technique, and can be edited in isetopzovano € |) itvpno-vnfsfmaaiosh {s systems, digital osshlpografin, telemetry device as vyvoaa 1shfrot 1x ciaHHbix with visual intsikatskey chpuchevoy on the screen of the tube (CRT) in Vice graphic and sign information. A device is known op. Research institutes on the screen of a CRT with RFID raster decomposition of raster rows, ooozhashee control unit, after the plug-up of the memory block,. a switch, a buffer memory block and a character generator, as well as a decoder block, a register block and a generator (lines. This device allows parallel display of signs and straight lines. C The disadvantage of this device is that it cannot display graphic information in the form of graphs. The closest to the invention to the technical essence is a device for recording information on a CRT screen, containing a synchronizer, a first memory block, successively connected blocks of a second beam, character generator, OR element, tue A swarm input of which is connected to the first output of the synchronizer, and a video conference device (ICS), the second input of which is connected to the second output of the synchronizer, and the ordinate register connected in series with the output of the first memory block, the second circuit of which is connected to the third output of the synchronizer and output with a third input of an IL element. A device with vertical decomposition of raster lines allows displaying signs and graphical information in the form of a graph G23. A disadvantage of the known device is that it ire allows displaying graphs with large numbers of discretization levels up to the ordinate axis, since the comparison time of the counter status code and the lock code located in the op register is: ty | limited by the time of the installation of all the counter and the delay of the processing of the comparison circuit. This limits the number of levels (1) on the ordinate axis, which, with a high resolution of the DCS, doesn’t allow the Gd to display with great accuracy. The purpose of the invention is to increase the speed of the device. The goal is achieved by information on the screen of the television and actuator, containing a synchronizer connected with the new and second memory blocks, character generator, this OR volume and the television indicator, the second memory block is connected to the signogen ator, nym to elements or connected to the. Using the talevizion indicator, the counters are introduced, the outputs of the parallel transfer of which are connected to the OR element, and the information and counting inputs are entered from a memory memory block and the synchronizer, respectively. At the firm. 1 shows a block diagram of the first device; in FIG. 2, a possible implementation of a self-locking counter. The device contains a synchronizer 1, the first memory block 2, a block 3 of counters, an element OR 4, a telemeter indicator 5, for example, a switchboard, a second memory block 6, a character generator 7, a bus 8 for input of graphic information and an input bus 9 for inputting an alphanumeric sign information. The device works as follows. The formation of izofazheni on the screen 5 VKU is carried out in accordance with the CII with the codes received by the turntable SHESH 8 and 9 of entering information in blocks 2 and b of the memory, respectively. During the reverse run of the electron beam along the raster line, precedes the forward run, block 2 of the first memory block is polled AND the ordinate codes of the graphs corresponding to this raster line are written to counters. During the forward path of the beam from synchronizer 1 to the counting inputs 3, a sequence of pulses arrives, which simultaneously enters the counting input of the synchronizer counter of synchronizer 1. When any counter is reapplied, it locks itself, and at the same time the pulse from the parallel output passes to one of the element inputs OR OR 4. So how are they formed? deosigna highlighting points of graphs by the raster lad. The unlocking of the counting counter is effected (it descends during the return path of the beam along the next cipoKe raster
