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

708 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!

I’m on my phone. But if you google how an old phone line modem modulates and demodulates digital to analog and back you’ll get some neat charts. And that will help visualize the difference.
