Sine and cosine wave generation in FPGAs

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 ...

Generate swept sine/cosine waveforms with two filters

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 Generates High-Frequency Sine/Cosine Waves From Square-Wave Input

This file type includes high resolution graphics and schematics. Although quite a few direct digital synthesis (DDS) ICs can generate high-frequency sine waves, their complexity excludes them from ...

Simple Generator Provides Very-Low-Frequency/Distortion Sine and Square Waves

The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...
