Frequency Modulation for Dummies
noun
pronunciation: 'frikwənsi_,mɑdʒə'leɪʃənWhat does Frequency Modulation really mean?
Frequency Modulation (FM) is a term used to describe a way that information, like sound or data, is transmitted through the air or wires. You know how a radio works, right? Well, it's like when you tune in to your favorite radio station, and you hear the DJ's voice or music playing. That sound you hear is being sent to your radio through frequency modulation.
So, let's break it down. Imagine you have a toy car, and you want to control it without touching it directly. How can you do that? Well, you can use a remote control, right? And how does that remote control work? It sends signals to the car using a special kind of wave called a radio wave. Now, in the case of frequency modulation, we use radio waves to send the information (like sound) from one place (like a radio station) to another (like your radio).
But what exactly happens during frequency modulation? Well, the information, such as the DJ's voice or an instrumental sound, is first converted into an electrical signal. This electrical signal is then used to change the frequency of a carrier wave. A carrier wave is like a vehicle that carries the information from one place to another. It's like a train that transports passengers (the information) from one station to another.
Now, imagine you're at the train station, waiting for a specific train. But suddenly, you notice that instead of just one train, there are many different trains running on different tracks. Each train represents a different frequency or pitch of sound. The frequency of a wave is like the pitch of a sound. So, when we change the frequency of the carrier wave, it's like changing the train track that the information hops onto.
Once the information hops onto the carrier wave, it travels through the air or wires to reach its destination. And just like how you can tune the dial on your radio to find different stations, when your radio receives the carrier wave, it knows how to "decode" it and turn it back into the original sound or information. It's like when your friend sends you a secret message written in a special code, and only you know how to decrypt it and understand what it says.
So, to put it simply, Frequency Modulation (FM) is a way of sending information, like sound or data, from one place to another using radio waves. It works by changing the frequency of a carrier wave, just like different trains running on different tracks at a train station. And when the information reaches its destination, it can be "decoded" and turned back into the original sound or data again.
