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 ...

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 ...

Based on Hertz elastic contact theory, the contact mechanics model of two cosine wave is established. The mechanical characteristics of the model in the elastic, elastic-plastic, and plastic stages ...

We’ve done quite a bit with Google Sheets and signal processing: we’ve generated signals, created filters, and computed quadrature signals. We can pull all that together into an educational model for ...
