Suppose you take a few measurements of a time-varying signal. Let’s say for concreteness that you have a microcontroller that reads some voltage 100 times per second. Collecting a bunch of data points ...

Don’t believe the hype. The digital revolution hasn’t conquered everything. We still need analog technologies to gather data and turn it into ones and zeroes, and the analog-to-digital converter (ADC) ...
