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 digital scope’s effective bandwidth of isn’t determined merely by analog componentsthe digitizer and memory also play a role When selecting an oscilloscope for a specific measurement, the first ...

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 ...

In previous installments of the AudioFile, we’ve talked about basic PCM audio, which encodes audio into a series of numbers that a computer can play or manipulate. We’ve also discussed the process of ...

If you haven’t come across compressive sensing, you will do soon. It’s a way of sampling and reconstructing an analogue signal at a rate far lower than standard information theory would deem possible.

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 ...
