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 ...

In part 1, we started to make some intuitive connections between near-Nyquist sampling, the addition of close-frequency sines, and how those signals would interact with perfect LP filters. Let's put ...

In this feature on the nature of analog and digital signals, DSP consultant Nalin Pithwa starts with an excerpt from the cruise of the Revolution to introduce the concepts of analog-to-digital ...
