The most important specifications for digitizers and oscilloscopes are bandwidth and sample rate. Acquisition memory length is not a premier specification, but it does dramatically affect both ...

Digital instruments sample analog waveforms and operate on the samples with the assurance that the data can be restored to continuous analog form. The sampling theorem states that a signal digitized ...

Replay: There's some amazing and rather beautiful science called for when we scale video and convert frame rates. This rather technical-sounding subject turns out to be a fascinating story. You'd be ...

As one of the cutting-edge research areas in modern physics, space-based gravitational wave detection aims at capturing gravitational wave signals in the mHz frequency band. A key technological ...
