Instead, one could modulate a carrier by changing its instantaneous frequency, which is frequency modulation or FM and is used for high-fidelity broadcasting. Yet another way to modulate a carrier is ...

In an article published in the American Physical Society journal Physical Review Letters, researchers reported observing unexpected instantaneous phase shifts during atomic scattering. By firing a ...

Thus, signals without epileptic fits gain in importance when it comes to supplementing the diagnosis" For this reason, in this study the authors obtain the instantaneous phase of the signals.

In an article published today (Thursday, Aug. 24) in the American Physical Society journal Physical Review Letters, researchers reported observing unexpected instantaneous phase shifts during ...
