Aliasing is thankfully becoming a less frequent problem due to improved instrument designs. Users should still be aware of it ...

If we want to take samples of some analog waveform, as in doing analog to digital conversions at some particular conversion rate, there is an absolute lower limit to the rate of doing conversions ...

Suppose you take a few measurements of a time-varying signal. Let’s say for concreteness that you have a microcontroller that reads some voltage 100 times per second. Collecting a bunch of data points ...

Bringing the concepts of pulse shaping and frequency combs together allows the generation of waveforms with both controllable ultrafast time structure and long-term coherence. Two-photon absorption ...
