How Does Difference between Analog and Digital Signals | AddOhms #6 Work?

Analog and digital signals are like messy drawings and color-by-number pictures, both show things, but in different ways.

Imagine you're drawing a wave on paper with crayons. That's like an analog signal, it can be any shade, any height, and it flows smoothly from one color to the next. It’s freeform and continuous, just like how water flows out of a tap, always changing, never stopping.

Now imagine you're using a color-by-number book. You only have certain colors to pick from, and you can only use them in specific spots. That's like a digital signal, it’s made up of on and off, or 1s and 0s, just like light switches. It jumps from one color to the next instead of flowing smoothly.

• Analog signals are like water in a river, always moving, always changing.
• Digital signals are like a clock ticking, it goes on and off, 1 and 0, never in between.

So when you're listening to music or watching TV, the difference between analog and digital is like the difference between drawing freely and coloring inside the lines, both work, but they do it in their own special way!
