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 ...

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 ...

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 ...

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 ...

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, ...
