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

698 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!

Turn on the water faucet and just let the water run. That’s an analog signal, because the water is continuously coming out, with no breaks.

Turn the water faucet on and off repeatedly. That’s a digital signal, because the water is coming out in discreet chunks, with breaks between each chunk.
