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 ...

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 ...

This triangle wave generator is made with a trigger Schmitt that converts a triangle wave into a rectangular one used to charge and discharge a capacitor through current sources. The positive current ...

…for I have used Analog Devices’ wonderful LTspice to have a quick look at the p-jfet and n-jfet versions of the Middlebrook & Richer trinagle to sine wave converter. And here are the results, both ...
