Physicists have transferred time and frequency information over a distance of more than 100 km in free space, far exceeding the previous record. The technique, which makes it possible to synchronize ...

This file type includes high resolution graphics and schematics when applicable. Author’s note: Early in my engineering career, I accepted a research project to characterize light transmission ...

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 modern, advanced CMOS direct radio frequency (RF)-sampling data converter has been eagerly awaited by system design engineers for several major end-equipment manufacturers. This includes ...

Editor's note: I am happy to bring you, my friend and former long-time colleague at Texas Instruments, Matthias Feulner, one of the best high-speed communications experts in the industry The latest ...

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 ...
