Scientists have proposed and experimentally demonstrated a ratchet concept to control the spin motion. In analogy to a ratchet wrench, which provides uniform rotation from oscillatory motion, such ...

Quantum stochastic rectification is a process observed in some physical systems, which entails the conversion of random quantum fluctuations (i.e., quantum noise) and a small oscillating signal, such ...

For the first time, scientists have detected an oscillating signal of a star being destroyed by a supermassive black hole. "You can think of it as hearing the star scream as it gets devoured," said ...

The “envelope” of an oscillating signal is a smooth curve outlining its extremes. We can use such an envelope to help us control our audio-reactive artifacts. As you may recall from my previous MEGEQ7 ...

Apple won a core multitouch patent regarding oscillating signals that was alluded to when Steve Jobs first announced the original iPhone in 2007, and adds to the company's already formidable legal ...

There is an art to making good measurements. In the ideal case, you want a really sensitive measuring device so that you can measure the smallest of changes to the signal you are interested in. But ...

Here this circuit is based on the principle of audio amplification using operational amplifier and pulse width modulation using 555 Timer. In this article we are describing the principle, design and ...
