The circuit works due to the fact that voltage increases or decreases linearly when a constant current flows into or out of a capacitor. If we manage to charge and discharge the capacitor with the ...

The frequency of the sawtooth is digitally programmable, so the design requires no external components to set the frequency. A DDS device, a programmable waveform generator, can deliver sine, square, ...

Also, triangular wave. An audio waveform theoretically comprised of an infinite set of odd harmonic sine waves. It is often used in sound synthesis where its timbre is less harsh than the square wave ...
