Determine the frequency of oscillation of the circuit above, and to what value must R1 be changed to make the frequency 20 kHz. To determine the frequency of oscillation of a triangular wave ...

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 ...

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 bargraph.

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 ...

It’s the most basic form of synthesis but there are still plenty of ways to spice up your sound design with virtual analogue… When you purchase through links on our site, we may earn an affiliate ...

Over on YouTube [Andrew Neal] has a Function Generator Build for Beginners. As beginner videos go this one is fairly comprehensive. [Andrew] shows us how to build a square-wave generator on a ...
