There are plenty of designs out there for sawtooth and triangle function generators, many of them using the humble 555 IC. Few are readily voltage controlled, making them difficult to work with using ...

I don’t have a signal generator, or more specifically I don’t have a low frequency signal generator or a function generator. Recently this fact collided with my innocent pleasure in buying cheap stuff ...

Unlike digital RF generators that produce only sine waves, function generators can produce repetitive waveforms of different shapes such as sine, square, triangular, sawtooth, and pulse. Function ...
