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

In: 1

Answer 1

All sound is analog.

While reproductions of particular sounds may be recorded and stored in digital mediums, when these are played back, the result is *analog* electrical signals which drive the speakers. Even when a speaker is fed directly with digital pulses, the resultant sound is an analog signal.

FM radio stations merely replace speakers with an FM radio transmitter.
