As we discussed at the beginning of this series, sampling has nothing to do with digitization, or quantization. A sampled signal can remain in the analog domain, though digitized signals are sampled ...

Digital signal processing is often a mystery to many people, but the underlying principles are fairly straightforward and within the grasp of anyone with a technical background. In this feature, we’ll ...

A software-defined radio (SDR) terminal promotes programmable realizations of the physical layer functionalities. A lot of research work has been done in applying DSPs and FPGAs to implement the ...

We casually speak of digital audio, often referring to it as AES audio, perhaps AES3 (for the number of the AES standard), or by an older term AES/EBU. But what exactly is this AES3 signal? Here’s the ...

When working with mixed-signal technology, you will find that the subject of dithering keeps showing up. Most engineers know that averaging “n” samples of an analog-to-digital converter (ADC) will ...
