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 the triangular-wave generator useful in sweep circuits and test equipment. For example, switched-mode power supplies and induction motor-control circuits ...

The circuit itself is built around a slow triangular-wave oscillator, that ramps the current up and down in the LEDs to make it look as if the lights are breathing in and out.

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

This circuit uses 10 LEDs to produce the effect of a single LED continuously moving back and forth in a line. The circuit comprises of two main parts, a triangle wave oscillator and an LED ...
