ELI5: Explain Like I'm 5

Eb/N0

Eb/N0 is a way to measure how good a signal is when it travels from one place to another. Imagine you are playing with your toy car and you want to know how far it can go before you can't control it anymore. Eb is like how much energy your toy car has to move forward and N0 is like how much noise or interference there is that could make your toy car stop or crash.

So, when someone talks about Eb/N0, they are really talking about how strong the signal is and how much it could be affected by noise and interference. It's like trying to talk on the phone with someone when you have a really bad signal - sometimes you can hear them clearly, but sometimes the sound gets all fuzzy and you can't make out what they are saying.

In conclusion, Eb/N0 is a way to measure how well a signal can travel through space and how likely it is to be disrupted by noise and interference. It's like trying to control your toy car in your playroom or trying to speak on the phone when you have a bad signal.
