Fiber-optic interferometric sensors have emerged as essential tools in precision measurement, utilising the interference of coherent light to detect minute displacements and variations in physical ...

[brmarcum] takes us back to analog building block basics with his Frequency Modulation and Demodulation tutorial. Frequency Modulation (FM) sounds simple at first, but understanding the electronics ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

The portion of the continuous RANGE of frequencies of electromagnetic radiation (i.e. oscillating electrical and magnetic energy which travels at the speed of light) used in broadcast TRANSMISSION.

Researchers at the US National Institute of Standards and Technology (NIST) have used atoms to decode digital signals encoded by phase modulation. The atoms, cesium in this case, are ‘Rydberg atoms’ – ...
