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 ...

We live in a noisy world. The noise can be self-induced, like an intrusive, buzzing alarm clock that gets us up to start the day. Or it can be natural noise, like chirping from a bird, or human-made ...

Digital transition switching is the primary cause of noise in mixed-signal devices. Signal noise and immunity to power, ground, and substrate noise all benefit from using differential circuits. Design ...
