Sub-Nyquist sampling and Finite Rate of Innovation (FRI) signal processing represent a paradigm shift in the acquisition and reconstruction of signals. Traditional sampling theories require adherence ...

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: Make sure you get your audio settings and recordings right with this important guide from Tim Dunphy. Sound often gets given the backbench within the video world. Whilst the concepts of ...

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 ...
