I want to make a sine and cosine wave in an FPGA. Now, I could use a CORDIC / NCO, but I need small. I don't need any particular frequency; I just need a sine/cosine wave. I used to have a spread ...

We are always excited when we see [Hamster] post an FPGA project, because it is usually something good. His latest post doesn’t disappoint and shows how he uses the CORDIC algorithm to generate very ...

In response to my recent blog asking about Sine and cosine wave generation in FPGAs, several folks expressed an interest in seeing the Spreadsheet I mentioned… so if this little rascal ever turns up I ...

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 ...

At a recent conference, I was given a sandwich wrap for lunch, and it was cut at an angle to display a bigger cross-section of the filling. When I unrolled it to get rid of some of the bulky tortilla, ...

If you’re a child of the ’80s or ’90s, chances are you’ve spent hours tracing out intricate patterns using the pens and gears of a Spirograph kit. Simple as those parts may be, they’re actually a very ...
