Embedded Systems: Kits for Kids
October 15, 2008 6:17 am | by Jon Titus, Senior Technical Editor | Articles | CommentsI'll begin this column with a recommendation: Start kits with a set of basic hand tools. When my son went to college, he had tools to hang pictures, connect TV sets and CD players, and tighten desks and shelves. As a result, he met most of the people on his co-ed floor. When our daughter went to college she got a tool kit, too. I suggest Phillips and flat-blade screwdrivers, pliers, diagonal cutters, wire strippers and a couple of adjustable wrenches. Later you could add a set of nut drivers, sockets wrenches and an inexpensive soldering iron.

Cover Story: DDS ICs and IP Make Waves
October 15, 2008 5:40 am | by Jon Titus, Senior Technical Editor | Articles | CommentsYou can think of direct digital synthesis as a technique that lets a digital value control the frequency of a sine wave. At its simplest, a DDS circuit involves a binary counter, a ROM programmed with equally spaced sine values for one full wave, and a digital-to-analog converter to convert the stored sine values to voltages. The frequency of the counter's clock determines the sine-wave frequency, but that's an inflexible arrangement.
