This Design Brief introduces a computationally efficient network that computes the derivative of a discrete time-domain (digital) sequence. While recursive differentiating networks exist, this article ...

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 ...

This article explains the principles and applications of continuous-time sigma-delta ADCs, while comparing their advantages and disadvantages with discrete-time versions. Sigma-delta analog-to-digital ...
