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 ...
In part 1, we started to make some intuitive connections between near-Nyquist sampling, the addition of close-frequency sines, and how those signals would interact with perfect LP filters. Let's put ...
Analog-to-digital converters (ADCs) sample analog signals and produce a value that corresponds to a “snapshot” of the signal at a specific time. By taking samples at regular intervals, you can obtain ...
