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 ...

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 ...

Abstract This chapter extends the continuous time sampling theorem of C. Shannon into discrete time signals and systems. We study the methods for down‐sampling the discrete time signals. We explain ...

The XMM-OM samples source properties on two distinctive time scales. Multiple exposures through a particular filter are often obtained during one pointing. They provide sampling on timescales between ...
