When you need to create simple pulses and don’t have a pulse generator, you can often substitute a function generator. By using a function generator’s triggered burst function, you can create pulses ...

Unlike digital RF generators that produce only sine waves, function generators can produce repetitive waveforms of different shapes such as sine, square, triangular, sawtooth, and pulse. Function ...

What do you do when you’ve got three broken function generators? Build your own, obviously. Since your workshop has already gone through three of these bad boys, you might find yourself repairing your ...

The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...

When working with hardware, whether a repair or a fresh build, it’s often necessary to test something. Depending on what you’re working with, this can be easy or a total pain if you can’t get the ...

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 ...
