Image interface circuit

Published:2011/8/10 3:58:00 Author:Nicole | Keyword: image | From:SeekIC

This circuit is used between computer and ordinary cathode ray oscillograph, the oscillograph phosphor screen displays an image composed of 512*512 dots, the image is stored in computer memory. The position of each dot is limited by two voltages, those voltages are transported to the V input terminal and H input terminal of cathode ray oscillograph. Two binary data words is fed to two A/D converter by computer, the voltage produced by converter is proportional to the value of these data words. These dots repeated display many times per second, so the produced image will not flash.
