Whenever I find myself harboring a constantly nagging thought, I know I will eventually have to get busy and find a way to put it to rest. When I read EDN’s Design Ideas, I look for the range of ...
On two days in the course of every year, one in March heralding the start of spring and another in September marking the first of fall, the Earth’s axis of rotation aligns perpendicular to the rays of ...
Over on YouTube [Andrew Neal] has a Function Generator Build for Beginners. As beginner videos go this one is fairly ...
Although quite a few direct digital synthesis (DDS) ICs can generate high-frequency sine waves, their complexity excludes them from many designs. However, designers can use simple high-frequency CMOS ...
Many microcontrollers or PICs will have uncommitted digital-to-analog converter (DAC) outputs that can be used to generate sine waves. But these are generally low resolution (8 to 10 bits), yielding a ...
