Basic jitter measurements using an oscilloscope

Jitter is a short-term variation in the timing of a digital signal from its nominal value. There are two main types of jitter, random jitter and deterministic jitter. Random jitter is unbounded, that ...

Ozone-depleting CFCs detected in historical measurements—20 years earlier than previously known

An international research team led by the University of Bremen has detected chlorofluorocarbons (CFCs) in Earth's atmosphere for the first time in historical measurements from 1951—20 years earlier ...
