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 ...

Closely related to a scope’s real-time bandwidth is its maximum specified sample rate. “Real-time” simply means that the scope can capture and display signals commensurate with the scope’s specified ...

Wideband signal processing and compressive sensing represent transformative approaches to the acquisition and reconstruction of signals across expansive frequency bands. Traditional methods that ...
