The distinction between analog and digital signals is very simple, but it can still be a challenge to wrap one's mind around the concepts that define the two systems. Just when you think you've got it ...

Digital Signal Processing (DSP) was, a few decades ago, a relatively obscure field associated with the mathematics of numerical analysis. As computers have become cheaper and faster, it is now ...

Up to this point in this series, we have examined the operational amplifier (op amp) and its use in several applications. To emphasize the diversity of the entire signal chain, this article opens the ...

How analog signal engineering is performed, in broad strokes. What are the component-selection considerations for new designs? What are VFAs and how are they used? Analog signal engineers specialize ...

What is an analog front-end (AFE)? Why use an AFE? AFE tradeoffs in energy-meter design. Sensors provide analog signals that need to be converted to digital values via analog-to-digital converters ...

Level-crossing analog-to-digital converters (LC-ADCs) represent an innovative approach to signal digitisation that departs from conventional uniform sampling. Instead of capturing signals at fixed ...
