Master Electronics provides availability of BK Precision’s 4075B series of arbitrary/function waveform generators. These devices incorporate a DDS architecture providing simple conventional function ...

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 ...

Hydrogen! It’s a highly flammable gas that seems way too cool to be easy to come by. And yet, it’s actually trivial to make it out of water if you know how. [Maciej Nowak] has shown us how to do just ...

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 ...

Cars use a type of a.c. generator, called an alternator, to keep the battery charged and to run the electrical system while the engine is working. A dynamo is another type of generator sometimes found ...
