This application note demonstrates nine different circuits that can be used to generate a sine wave. The first, a phase shift oscillator, is shown below. To view the application note, click on the URL ...

Microcontroller addict [Debraj] decided to make his own programmable sine wave generator, and was able to put it together for under $40 USD. Other than low-cost, his list of requirements was as ...

The circuit of Figure 1 produces an accurate variable-frequency sine wave for use as a general-purpose reference signal. It includes an 8th-order elliptic, switched-capacitor lowpass filter (IC3) that ...

In which we embark on a quest to forge a precise triangle wave, and use that to help set a gold standard for fake sine waves. How well will we fare? A while ago, I needed (or wanted) a pocket-sized ...

In DDS-mode, only a few commands are needed to e.g. generate a sine wave (orange block), accelerate the frequency (blue block) and lower the amplitude (green block). 23 different AWGs are able to use ...

I have a MIDI keyboard hooked up to GarageBand, and I'd like to use it to generate pure sine wave tones using the standard piano frequencies ...
