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 ...

Function generators (FGs) are measurement instruments in the category of waveform sources. They grew out of both a need for a versatile source of multiple waveshapes and from some interesting analog ...

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 when we ...

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 ...

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, ...

Spare a moment’s pity for the process engineer, whose job it is to keep industrial automation running no matter what. These poor souls seem to be forever on call, fielding panicked requests to come to ...

It never fails — we post a somewhat simple project using a microcontroller and someone points out that it could have been accomplished better with a 555 timer or discrete transistors or even a couple ...

For a long time, I have thought that pulse generator outputs should not have adjustable amplitude and offset. Instead, they should have an adjustable top value and a separately adjustable bottom value ...
