ELi5: What is the difference between analog and digital signals?

680 views

Or at least “explain it like I am an 8th grader.” I am a middle school science teacher and am struggling with explaining these concepts in a simplified way that my students can understand. They have some prior knowledge about waves and how they travel. I appreciate any help you can provide!

Analog signals are more like a dimmer switch for the light, where you can make it as bright or as dim as you want. It’s like having a light that can be a little bit bright, somewhat bright, very bright, or anywhere in between.

Digital has just two options (on or off), while analog can have lots of options (from a little bit to a lot).
