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 ...

Using these engines, we demonstrate an electricity generator that rests on water while harvesting its evaporation to power a light source, and a miniature car (weighing 0.1 kg) that moves forward ...

It’s easy to have a soft spot for “mini” yet perfectly functional versions of electronic workbench tools, like [David Johnson-Davies]’s Tiny Function Generator which uses an ATtiny85 to ...

A description of a four-phase RC oscillator of a sinusoidal and rectangular shape is given. A triangular-shaped signal is obtained by the counterphase addition of half-waves of sinusoidal signals ...

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

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 ...

The 1510A signal generator includes both charge and voltage signals to simulate a wide range of sensors and transducers. It also includes functions like adjustable frequency, multiple wave shapes, ...
