The result is a cheap function generator you can build with a Pi Pico and a handful of resistors, which will probably cost you the grand total of $12.

If you have a modern function generator on your bench it is quite likely to contain a direct-digital synthesis circuit that creates arbitrary waveforms using a microprocessor controlled DAC. If ...

Anyone searching for a function generator may be interested in a new DIY Arduino project which details how you can make your very own. “A function generator is a very useful tool, especially ...

Commercial curve tracers have existed for decades. But designers without access to one can create a simple circuit that uses a function generator and oscilloscope to generate JFET transfer and ...

A dead Tek FG503 function generator plug-in inspires a teardown. The culprit? A bad op amp in the power supply.
