Examples are microwave-assisted switching of magnetic structures and the generation of spin currents at low bias fields by high ... spin-wave modes with fast oscillations of the amplitude and ...

Relatively small kidney stones are often treated via shock wave lithotripsy (SWL), which involves delivering high-amplitude, low-frequency ultrasound waves to a stone for up to an hour ...

You need to know about these quantities used in waves - what they mean, the symbols used for them and the units used to measure them. Don't get confused with this quantity frequency. It is not a ...

A loud sound has a large amplitude, a high pitched sound has a high ... and makes the air vibrate quickly , so the wave peaks are closer together. A low pitch sound makes the air particles vibrate ...

It uses a phase-shift oscillator with a low-pass phase-shift network configuration rather than the more-common high-pass network ... frequency sine- and square-wave generator requires few ...

This Design Idea provides a simple, inexpensive, portable circuit as an alternative to a microcontroller to provide a wide-range source of low-distortion sine waves for audio-circuit ... method of ...

Because the atrial rate is so fast, and the action potentials produced are of such low amplitude, P waves will not be seen on the ECG in patients with atrial fibrillation. At times, the P wave ...
