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 ...

Analog behavior is difficult to compress into simple pass/fail decisions that could reduce redundant coverage.

Past columns have discussed sampling analog signals and analog-to-digital converter (ADC) technologies. In my experience, though, engineers who simply want to use ADCs rather than design with them, ...

The BlasterAmp [1] has proven useful to me in testing all sorts of analog-to-digital converter (ADC) circuits, even my digital oscilloscopes. While I mainly conceived it to test integrated ADCs in ...

Here are some interesting points regarding Equation 1. First, there is no direct dependence on sample frequency. However, the integration of phase-noise to calculate jitter depends on the sample ...

It’s a well-known conundrum that while most computers these days are digital in nature, almost nothing in nature is. Most things we encounter in the real world, whether it’s temperature, time, sound, ...

A look at the design of traditional ADC front ends. How to simplify the input drive of CTSD ADCs. Simplifying reference and reference-drive designs. In this article, we will use the terms “sensor” or ...

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 ...
