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 ...

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 ...

The integral role of software-defined radios in today's RF design. Why is an analog-to-digital converter such a key factor in SDRs? How to minimize SFDR to maximize ADC performance with a novel ...
