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 ...

I hereby declare 2005 “The year of the waveform generator” because of the unusually high number of product introductions. I've identified eight companies that have introduced function or arbitrary ...

When working with test equipment such as oscilloscopes and function generators, it can be useful to take a screen capture. Historically this was done with Polaroid cameras that were bolted in place, ...

Test applications often call for a clock signal. Rather than tie up a function generator, you can build a programmable clock generator with just two ICs. You can then control the clock generator with ...

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 ...
