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 ...

If we want to take samples of some analog waveform, as in doing analog to digital conversions at some particular conversion rate, there is an absolute lower limit to the rate of doing conversions ...

Digital oscilloscopes are normally operated in real-time acquisition mode, where the analog input is sampled and digitized at a user-selected sampling rate and written continuously into the ...
