A frequency multiplier is like a magic wand that can make sound or radio waves go faster. Imagine you have a toy car that you want to make go faster. If you push it harder, it goes faster, right? Well, a frequency multiplier works kind of the same way.
You start with a sound or radio wave that is moving at a certain speed. This speed is called the frequency. It's like the speed limit on the road. A frequency multiplier takes that wave and makes it go faster by adding more waves to it. It's like putting more engines on your toy car!
These extra waves are called harmonics, and they make the original wave bounce back and forth more times, making it go faster. It's like when you swing on a swing set. If you have someone pushing you, you go higher and higher with each push. That's what the harmonics do to the original wave.
So, in summary, a frequency multiplier is a tool that adds extra waves, called harmonics, to a sound or radio wave to make it go faster. Kind of like putting more engines on a toy car!
