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 previous installments of DSP Spreadsheet, we’ve looked at generating signals, mixing them, and filtering them. If you start trying to work with DSP, though, you’ll find a topic that always rears ...

Demodulators, directional circuits,and other electronics applicationsoften need two sine waves witha 90° difference in phase—a sine waveand its cosine wave. Engineers typicallyuse analog filters to ...

Circuit simulation and software workbooks like Matlab and Jupyter are great for being able to build things without a lot of overhead. But these all have some learning curve and often use clever tricks ...
