An example of this course of is a disc jockey’s voice being impressed into a ninety six MHz service wave utilizing frequency modulation (the voice would then be obtained on a radio because the channel “ninety six FM”). In addition, modulation has the advantage that it might use frequency division multiplexing . In the instance above, the “free area channel” has been divided into communications channels according to frequencies, and each channel is assigned a separate frequency bandwidth during which to broadcast radio waves. This system of dividing the medium into channels based on frequency is known as “frequency-division multiplexing”. Another time period for a similar concept is “wavelength-division multiplexing”, which is more commonly utilized in optical communications when multiple transmitters share the same bodily medium. For instance, in a radio broadcasting station the station’s giant power amplifier is the transmitter; and the broadcasting antenna is … Read More
