To follow up last week’s discussion on real-time versus equivalent-time oscilloscopes, I asked my colleague Pavel Zivny to send along his thoughts. Pavel, who’s a domain expert for high-speed ...

Stratified random sampling is a method of sampling that divides a population into smaller groups that form the basis of test ...

Real-time sampling oscilloscopes let you see the details of a waveform because they capture details, especially when your waveform isn’t repetitive. Equivalent-time sampling oscilloscopes generally ...

A simple random sample is a subset of a statistical population where each member of the population is equally likely to be ...

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 ...

Primetime crime drama meets reality in new forensic research. Scientists are using the new Direct Analysis in Real Time mass spectrometry interface, which has made a guest appearance on the popular ...
