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 ...

Ocean Insight’s Liquid Transmission Measurement System (LTMS) provides real-time, in-line monitoring of liquid colouring and coating applications used across the consumer electronics and food ...

Astronomers have now observed the radio emission from the neutral hydrogen gas (HI) in a nearby galaxy. Hydrogen gas emits radio emission in a spectral line at a very specific frequency of 1420 MHz.

Astronomical measurements of motion frequently utilize the Doppler effect, observing shifts in wavelength (or frequency) of emitted waves from moving sources, analogous to a changing siren pitch.

Many digital-communications systems use non-return-to-zero (NRZ) signaling, and system designers have created many NRZ test patterns to test and verify their products. These patterns usually either ...
