I needed to make a really low-cost swept frequency tone generator using just some spare op-amp sections and no parts that were sole source. Fortunately, the sweep requirements weren't terribly ...

[Eric Wasatonic] had a box of SWB2433 transistors that he had very little information about. In order to discover their properties, he fired up his curve tracer to compare these transistors with more ...

Many systems divide a crystal frequency by an integer number to generate clock signals. Unfortunately, the integer divisor limits the available set of output frequencies. Applications such as ...
