Over on YouTube [Andrew Neal] has a Function Generator Build for Beginners. As beginner videos go this one is fairly ...
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 ...
Sawtooth- or exponential-ramp relaxation oscillators are common and generally easy to build. However sometimes a cleaner waveform is desired, and generators of even-symmetric waveforms are a bit more ...
