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 ...

The model 4040DDS sweep/function generator uses direct digital synthesis (DDS) to generate precise and accurate waveforms with little distortion. The $699 instrument provides 20-MHz sine and square ...
