What’s the simplest audio frequency oscillator you can imagine? There’s the 555, of course, and we can think of a few designs using just two transistors or even a few with just one. But… ...

For almost a hundred years, physicists suspected the answer was yes, but they couldn’t describe it properly without breaking ...

In this case, it’s another, even simpler audio oscillator, this time with just a loudspeaker and a battery.

The Dove Audio Waveplane Oscillator module has launched via Kickstarter this week is already over halfway towards its required pledge goal. Pledges are available from £375 and worldwide ...

Caltech scientists have created a hybrid quantum memory that converts electrical information into sound, allowing quantum states to last 30 times longer than in standard superconducting systems. Their ...

Caltech (California Institute of Technology) researchers have developed a hybrid quantum memory that stores information from superconducting qubits as sound, significantly extending storage time. They ...

The conversion from audio or video to FM takes place in the internal base-emitter junction capacitor by its parametric action, and the changes of the junction capacitor due to audio-to-video ...

A failing electrolytic coupling capacitor could be limiting the low frequency response, causing the station sound “tinny.” Audio proofs of the past uncovered these problems that might have otherwise ...

Mohammad Mirhosseini's lab at Caltech has paired a superconducting qubit on a chip with a miniature tuning fork, ...
