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 ...

When you are trying to digitize a modulated RF signal, you have several choices: you can heterodyne the signal down to a lower intermediate frequency (IF) one or even twice, then digitize; you can ...

The relationship between a signal’s constituent frequencies and the sampling rate used to quantize them is fundamental. As shown in Figure 1, sampling a signal that has a given spectrum creates a ...
