In recent years, digital electronics has made major progress and it has reduced the role of analog electronics substantially. It is a long time since the DTL and TTL digital gates have appeared and various micro controllers with different prices are available everywhere. From PAL and GAL to CPLD and FPGA many powerful components have been introduced. With these parts it is possible to respond to many processing and control issues. In Raytoun, we have the ability of analyzing, designing and simulating digital electronic systems and other related circuits and boards and with our experience in this field we try to meet the project requirements in the best and fastest possible way.
