Sometimes the need arises to construct a really simple oscillator. This could hardly be simpler than the circuit shown here, which uses just three components, and offers five separate octaves, ...

This Design Idea demonstrates a simple way to generate a multiphase clock signal, the frequency of which can be varied with minimal change in phase shift(s). The phase shift of the second output can ...

If there’s one thing that amateur radio operators are passionate about, it’s the search for the perfect sine wave. Oscillators without any harmonics are an important part of spectrum hygiene, and ...

From its inception, the synthesizer has been a forward-looking instrument; it was a tool specifically designed to generate new and unheard sounds. When the synthesizer was new, many people tried to ...
