Category:Multiplexing

The combining of two or more signals into a single wave from which the signals can be individually recovered. Examples include time division multiplexing and frequency division multiplexing

Subcategories

• Code division multiplexing - the use of codes to combine multiple communications signals into a single signal over a single line and to divide them for further transmission, as opposed to frequency division multiplexing
• Demultiplexing - a method used to extract multiple signals from a single line to be transmitted to receivers
• Frequency division multiplexing - or FDM, a form of signal multiplexing that involves assigning non-overlapping frequency ranges to different signals
• Multiplexing equipment - equipment that can combine or divide multiple signals for transmittal
• OFDM - orthogonal frequency-division multiplexing, the use, by a single transmitter, of a set of frequency multiplexed signals with the exact minimal amount of frequency spacing to prevent interference
• Time division multiplexing - or TDM, a type of digital multiplexing in which two or more streams of information are transmitted at what seems to be the same moment, but that take turns on that channel
• Wavelength division multiplexing - or WDM, a technique which multiplexes numerous signals onto an fiber-optic wire using different wavelengths (colors) of laser light
