Pulse (signal processing)

Okay kiddo, have you ever heard a song or a sound that goes up and down very fast, like a heartbeat? We call that sound a pulse. In signal processing, a pulse is a signal that repeats itself like a heartbeat. It can be used to send information or control systems.

Now imagine you have a toy car that you want to control using a remote. The remote sends a pulse signal to the car telling it what to do. If you press the button on the remote once, it sends a short pulse signal that tells the car to move forward. If you press and hold the button, it sends a longer pulse signal that tells the car to keep moving forward.

In electronics, the pulse can also be used to measure time or distance. For example, let's say you want to measure the distance between two objects. You can send out a pulse signal (like a sound wave) and time how long it takes for the signal to bounce back. The longer it takes to bounce back, the farther apart the objects are.

In conclusion, a pulse signal is a repeating sound or electronic wave that can be used to control systems, send information, or measure time and distance. It's like a little heartbeat for electronics!
