Pilot signal

Imagine you are playing hide and seek with your friends. You are hiding in a closet and you make a noise so your friends can find you. That noise is like a pilot signal.

In the world of electronics, a pilot signal is like that noise that helps electronic devices find each other. It is a special kind of signal that is used to help devices, like smartphones or TVs, communicate with other devices.

Just like you can't find your friends without making a noise, electronic devices can't communicate with other devices without a pilot signal. This signal is sent out constantly by the device, and other devices (like a Wi-Fi router) use it to locate and connect with that device.

So remember, a pilot signal is like a noise that helps electronic devices find each other so they can talk to each other!
