This Design Idea avoids the RC charging waveshape of a standard relaxation oscillator, replacing it with a linear rise/fall triangle wave. Positive feedback is used to increase the charging rate over ...

The linearity of triangular waveforms makes triangular wave generators useful in many “sweep” circuits and test equipment. For example, switched-mode power supplies and induction motor-control ...

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 ...
