In Part 1, I discussed the background behind lock-in amplifiers. Here, I’ll cover analog and digital lock-in amplifiers, software-defined radio, de-embedding, and the hardware and software ...

When is it permissible to use an equipment grounding conductor, not larger than 14 AWG copper or its equivalent, to ground a wireway or auxiliary gutter? A. Where the wireway or auxiliary gutter does ...

Synthetic biologists have added high-precision analog-to-digital signal processing to the genetic circuitry of living cells. The research dramatically expands the chemical, physical and environmental ...

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 ...

The notion of “signal processing” might seem like something impenetrably complex, even to scientists. However, the fact is that most of them have already being doing it for a long time, albeit in an ...
