Question

How are radio stations able to turn digital music into radio waves?

In: 1

Answer 1

The radio waves stations send have two parts: the sound waves, which are self explanatory, and the carrier wave, which is like an identifer for each station. In fact, these carrier waves are where station numbers come from (like 1080 or 100.5).

The station will broadcast signals that combine the sound and carrier waves together. When you tune your radio, you’re asking it to look for a signal with a specific carrier wave. As the radio picks up those signals, it removes the carrier wave and keeps the sound waves, which it then plays as music.
