All periodic signals can be described in terms of amplitude and phase. We all learned that in basic circuit theory. You surely recall having to calculate signal’s phase change when it passed through a ...

The bright, spatially coherent radiation emitted by a laser can be found in numerous research applications, such as spectroscopy, photochemistry, communications, imaging and material processing.

The development of a real-time optical waveform measurement technique with quantum-limited sensitivity, unlimited record lengths and an instantaneous bandwidth scalable to terahertz frequencies would ...

An arbitrary waveform generator (AWG) is a powerful and flexible signal source capable of generating any wave shape within the bandwidth and amplitude range of the generator. Populating an AWG with ...

Some brief theory and typical measurements of phase noise. Standard analysis of PLL phase noise used by most CAD applications. How to produce the lowest phase noise at a PLL output. A standard design ...

Just because harmonics is becoming a more prevalent problem, that doesn't mean the subject is getting any easier to understand Harmonics are AC voltages and currents with frequencies that are integer ...

A PQ expert can link an abnormal current or voltage waveform to an abnormal condition on a power system just as a handwriting expert matches a signature to a person. Many facilities now have online ...
