Once upon a time, if you wanted to generate some waveforms, you needed to buy an expensive off-the-shelf function generator or whip up a big pile of analog electronics. Not so today, when you can grab ...

A lifetime of amassing random pieces of test equipment has left me with a gap in my armoury, namely that I don’t possess a low frequency function generator. This could easily be addressed, but for two ...

The more common approach to manipulate the incoming AC wave so that both halves are used to cause output current to flow in the same direction is the use of full-wave rectifiers. A full-wave rectifier ...
