Phase detector

Alright, kiddo. So do you know what phases are? Imagine you and your friend are jumping on a trampoline. When you jump at the same time, you're in the same phase. But if your friend jumps while you're still on the trampoline, you're in different phases.

Now, a phase detector is like a special device that can tell if something is in the same phase as something else. It looks at two signals and compares them to see if they're in sync or not.

Why is this important? Well, sometimes we need different signals to work together and be in sync. For example, in electronics, we might use a phase detector to make sure two different signals are properly aligned.

So, in short, a phase detector is a tool that helps us make sure different signals are in sync with each other.
