One could, for instance, think of the commercial AM or FM locally as an FDM system. In telephony, using a bank of filters it is possible to get several users in the same system—it is, however, necessary to have a similar system at the receiver to have a two way communication. Frequency-division multiplexing (FDM) is a scheme in which numerous signals are combined for transmission on a single transmission line or channel. Each signal is assigned a different frequency (subchannel) within the main channel. Definition: Frequency division multiplexing is a multiplexing technique in which multiple separate information signals can be transmitted over a single communication channel by occupying different frequency slots within common channel bandwidth.

Definition: Frequency division multiplexing is a multiplexing technique in which multiple separate information signals can be transmitted over a single communication channel by occupying different frequency slots within common channel bandwidth. FDM technique is basically used for muxing of analog signals. Frequency-Division Multiplexing (FDM) is a signal transmission technology in which multiple signals can simultaneously be transmitted over the same line or channel. Frequency-division multiplexing (FDM) can be used in both wired and wireless networking for transmitting large amounts of data at high speeds. A frequency division multiplexing operates in a similar way to radio broadcasting where a number of different stations will broadcast simultaneously but on different frequencies.
In telecommunications, frequency-division multiplexing (FDM) is a technique by which the total bandwidth available in a communication medium is divided into a series of non-overlapping frequency bands, each of which is used to carry a separate signal.This allows a single transmission medium such as a cable or optical fiber to be shared by multiple independent signals.

Starting in the early 1950s, frequency-division multiplexing was used to send up to 5,400 telephone channels on each microwave radio channel, with as many as ten radio channels combined into one antenna for the hop to the next site, up to 70 km away. Microwave-Wikipedia
A coherent wavelength-swept light source is necessary to acquire the reflection spectrum; Frequency Division Multiplexing • FDM is derived from AM techniques in We divide it into four channels, each channel having 1M/4=250-kHz bandwidth.

FDM achieves the combining of several signals into one medium by sending signals in several distinct frequency ranges over a single medium. Frequency Division Multiplexing (FDM) sistem FDM, umumnya terdiri dari 2 peralatan terminal dan penguat ulang saluran transmisi (repeater transmission line): Peralatan Terminal (Terminal Equipment) Peralatan terminal terdiri dari bagian yang mengirimkan sinyal frekuensi ke repeater dan bagian penerima yang menerima sinyal tersebut dan mengubahnya kembali menjadi frekuensi semula. Frequency-hopping spread spectrum (FHSS) is a method of transmitting radio signals by rapidly changing the carrier frequency among many distinct frequencies occupying a large spectral band. The changes are controlled by a code known to both transmitter and receiver . FDM or Frequency Division Multiplexing is a networking method of sharing the total available bandwidth of any communication channel by diving them into many non-overlapping bands of frequency.

Frequency-Division Multiplexing (FDM) is a signal transmission technology in which multiple signals can simultaneously be transmitted over the same line or channel. Frequency-division multiplexing (FDM) can be used in both wired and wireless networking for transmitting large amounts of data at high speeds. Multiplexing is a technique in which several message signals are combined into a composite signal for transmission over a common channel. In order to transmit a number of these signals over the same channel, the signals must be kept apart so that they do not interfere with each other, and hence they can be separated easily at the receiver end. This video discusses Frequency Division Multiplexing (FDM).
