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 ...

The output frequency can be set precisely and it can also be used as a sweep generator to test the frequency response of audio circuits, and more. I’d like to talk some more about the real build of a ...

Meanwhile, Deavenport needed a slow ramp circuit to test the DVM he was developing. So he designed a simple function generator using circuitry that had been around a long time. Deavenport's circuit ...

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 ...
