Frequency Division Multiple Access

• You can think of radio stations signals stacked up next to each other in the frequency domain.
• This method of allowing several signals to be transmitted simultaneously is called Frequency Division Multiple Access.
• Acronym: FDMA.
• When you tune your radio to a particular station, you actually tune a bandpass filter to let only the signal from your favorite radio station pass.
