Digital signal processing (DSP) refers to various techniques for improving the accuracy and reliability of digital communications. This can involve multiple mathematical operations such as compression ...

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 ...

For continuous and stable signals, here’s how to integrate the digital-to-analog converter DAC7821 with the TL082 operational amplifier.

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 ...

Bede Liu, an emeritus professor of electrical engineering and a pioneer in digital signal processing, died on May 7. He was 91. Liu’s pathbreaking research aided the transition from analog to digital ...

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 ...

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 ...
