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, ...

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 ...

Sometimes the best projects are the simple, quick hits. Easily designed, fast to build, and bonus points for working right the first time. Such projects very often lead to bigger and better things, ...

Chaos Theory has been an important pursuit of physicists and mathematicians since it was brought to the forefront as a distinct phenomenon in the early 1960s. This early exposition got the attention ...

Using this Pierce-oscillator circuit, users can test and verify the basic operation of a crystal in parallel-resonance mode. It allows the user to calculate and set the critical external capacitor ...

Figure 1: Superconducting qubit–oscillator circuit. Figure 3: Selection rules and transmission spectrum around the symmetry point. In conclusion, we have experimentally achieved deep strong coupling ...

Neuroscientists discovered the mechanism underlying the oscillator circuit that controls the rhythmic extension and retraction of whiskers in mice. Many of our bodily functions, such as walking, ...
