frequency division multiplexing in a sentence

Examples

1. Before the digital T-1 system, carrier wave systems such as 12-channel carrier systems worked by frequency division multiplexing; each call was an analog signal.
2. With ADSL, the modem and the DSLAM communicate by a protocol called discrete multitone modulation ( DMT ), which is a form of frequency division multiplexing.
3. "' DVB-T "'uses coded orthogonal frequency division multiplexing ( COFDM ), which uses as many as 8000 independent carriers, each transmitting data at a comparatively low rate.
4. can u explain me in detail the pulse width modulation using frequency division multiplexing ?  Preceding contribs ) 02 : 24, 4 April 2011 ( UTC)
5. A wide-band data link from the gateway to the user terminal employs an Orthogonal Frequency Division Multiplexing ( OFDM ) with a Time Division Multiplex ( TDM ) overlay.
6. By using frequency division multiplexing, an HFC network may carry a variety of services, including analog TV, digital TV ( SDTV or HDTV ), video on demand, telephony, and high-speed data.
7. Flash-OFDM, which stands for Orthogonal Frequency Division Multiplexing, has other attributes beyond speed : It was designed to work well in moving cars and trains while requiring less spectrum than some wireless technologies.
8. Telephone trunk lines, and especially frequency division multiplexing carrier systems, are usually 4-wire circuits rather than 2-wire circuits ( or at least they were before fibre-optic became widespread ) and require a different kind of cable.
9. Analog and digital modulation facilitate frequency division multiplexing ( FDM ), where several low pass information signals are transferred simultaneously over the same shared physical medium, using separate passband channels ( several different carrier frequencies ).
10. At the core of the coalition is the technology called Vector Orthogonal Frequency Division Multiplexing-- which Cisco says delivers two-way data, voice and video communications over the air with speed and quality comparable to today's cable networks.
