1 Modulation and Multiplexing Broadband Transmission – A carrier is a high frequency signal that is modulated by audio, video, or data. – A radio-frequency (RF) wave is an electromagnetic signal that is able to travel long distances through space.

2 Modulation and Multiplexing Broadband Transmission – A broadband transmission takes place when a carrier signal is modulated, amplified, and sent to the antenna for transmission. – The two most common methods of modulation are: Amplitude Modulation (AM) Frequency Modulation (FM) – Another method is called phase modulation (PM), in which the phase angle of the sine wave is varied.
