May 30, 2023 · Radio waves control everything from AM/FM broadcasts to wireless networks to garage door openers. William Taufic/Getty Images. Electromagnetic radio waves are one of the most significant discoveries for 20th and 21st century technology. You don't see them, but countless high frequency waves are bouncing through the air around you every day. They facilitate wireless communication for things ...

How does a radio system work?
Any radio setup has two parts: The transmitter takes some sort of message (it could be the sound of someone's voice, pictures for a TV set, data for a radio modem, etc.), encodes it onto a sine wave and transmits it with radio waves. The receiver receives the radio waves and decodes the message from the sine wave it receives.

How does a car radio amplify a DJ's voice?
When you tune your car's AM radio to a station — for example, 680 on the AM dial — the transmitter's sine wave is transmitting at 680,000 hertz (the sine wave repeats 680,000 times per second). The DJ's voice is modulated onto that carrier wave by varying the amplitude of the transmitter's sine wave.

How are different radio signals separated?
Each different radio signal uses a different sine wave frequency, and that is how they are all separated. Any radio setup has two parts: The transmitter takes some sort of message (it could be the sound of someone's voice, pictures for a TV set, data for a radio modem, etc.), encodes it onto a sine wave and transmits it with radio waves.

How do radio tuners work?
Tuners work using a principle called resonance. That is, tuners resonate at, and amplify, one particular frequency and ignore all the other frequencies in the air. It is easy to create a resonator with a capacitor and an inductor. The tuner causes the radio to receive just one sine wave frequency (in this case, 680,000 hertz).

How does a DJ's voice work?
The DJ's voice is modulated onto that carrier wave by varying the amplitude of the transmitter's sine wave. An amplifier amplifies the signal to something like 50,000 watts for a large AM station. Then the antenna sends the radio waves out into space.

Why do we rely on radio waves?
Even things like radar and microwave ovens depend on radio waves. Communication and navigation satellites would be impossible without radio waves, as would modern aviation — an airplane depends on a dozen different radio systems. The WiFi networks that we depend on at work, home and school also rely completely on radio waves for data transmission.

Millions of radio waves--carrying sound wave signals and digital signals--reach your receiver every second. The receiver's tuner picks out a specific signal. Its amplifier strengthens that signal. A demodulator separates the signal from the carrier wave. And then a speaker converts the signal to the sound waves that you hear!
