When you buy the do-it-yourself kit, it requires a little solder work, and you will get everything needed to complete the project. The packet also includes a pretty good transparent acrylic enclosure, ...

Simple triangle-wave generators have a weakness in that the waveform of their output signal normally cannot be modified. The circuit presented here makes it possible to smoothly alter the waveform of ...

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 you ...

A function generator is a handy piece of test equipment to have on-site. [Kammenos] designed and built his own function generator, using the bench itself as the enclosure. You can see above that the ...

This circuit, a modification of a function-generator circuit, comprises a battery-powered sinewave generator that is continuously adjustable from 100 Hz to 10 kHz. We needed a handheld, ...

This all-analog circuit provides three key waveforms simultaneously and at the same frequency within the audio band. It is useful for evaluating audio systems, transformers, cables, and other ...
