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 ...

A look at the Nyquist sampling theorem. How to deal with aliasing by attenuating signals using low-pass filters (i.e., an antialiasing filter, or AAF). AAF requirements for different ADCs. A deep dive ...

A research team has developed a novel multidimensional sampling theory to overcome the limitations of flat optics. The study not only identifies the constraints of conventional sampling theories in ...

A research team at POSTECH has developed a novel multidimensional sampling theory to overcome the limitations of flat optics.

Requirements for different types of sample rates. Conversion techniques for these different sample rates. Synchronous and asynchronous sample-rate conversion. This article starts with an overview of ...
