Consider a transmission system using frequency division multiplexing What Cost factors are involved in adding one more pair of stations to the system?

In many cases, the cost of the transmission medium is large compared to the cost of a single transmitter/receiver pair or a modulator/demodulator pair. If there is spare bandwidth, then the incremental cost of the transmission can be negligible. The new station pair is simply added to an unused sub channel. If there is no unused sub channel it may be possible to re divide the existing sub channels creating more sub channels with less bandwidth. If, on the other hand a new pair causes a complete new line to be added then the incremental cost if large indeed.

Which multiplexing technique transmits digital signal?
In analog transmission, signals are commonly multiplexed using frequency-division multiplexing (FDM)
Name the various types of multiplexing techniques?
Multiplexing techniques vary widely based on what is being multiplexed. Modern telecommunications use a very wide array of techniques including: TDM - examples: TDMA, T-carrier FDM - examples: DWDM Spatial - example: MIMO Code division - examples: CDMA Phase or polarization division - cable/satellite TV Statistcal - examples: packet mode (STS), FHSS etc etc. This is far from a complete list. I think the question needs to be more specific.
How is interference avoided by using FDM?
Interference is avoided under frequency division multiplexing by the use of guard bands, which are unused portions of the frequency spectrum between subchannels. by abdullahi yusuf gedi
How is SDM typically realized and combimed with FDM?
Typically, space-division multiplexing (SDM) is realized through a set number of frequency bands. This is combined with FDM because cells neighboring those in the SDM are unable to share the same frequencies.
What is the bandwidth capacity of one strand of fiber optic?
Approximately 14 Tera bits per second over 160 Km using wavelength division multiplexing and rising every year as multiplexing techniques develop.
Which multiplexing technique transmits digital signal?
In analog transmission, signals are commonly multiplexed using frequency-division multiplexing (FDM)
Which of the three multiplexing techniques arre used to combine digital signals?
Frequency-division multiplexing, wavelength-division multiplexing, and time-division multiplexing.
What is mean by orthogonal frequency code division multiplexing in wireless communication?
Orthogonal frequency division multiplexing is special case of frequency division multiplexing where a ling serial data streams are divided into parallel data streams and each data stream is multiplied either by orthogonal frequency or code. when multiplied by code known as frequency code division multiplexing and when multiplied by orthogonal frequency then know as orthogonal frequency division multiplexing
Which of the three multiplexing techniques are used to combine analog signals?
Frequency-division multiplexing and wavelength-division multiplexing
What is 'ofdm'?
Orthogonal frequency-division multiplexing
What is the definition of the word 'multiplexing'?
Multiplexing is the process of combining multiple signals over one media line. There are several types of multiplexing: frequency division, time division, and wavelength division.
What type of multiplexing does cable tv use?
Does Cable television use time-division multiplexing

Why broadband are used in frequency division multiplexing?
Frequency division multiplexing is when a communication medium divides its frequency in order to carry a number of different signals at once. Broadband DSL uses this to transport large amounts of data quickly.
Advantages of synchronous time division multiplexing and frequency division multiplexing in computer netwoeks?

What are the differences between broadband and baseband?
Baseband Signalling: 1)Uses digital signalling 2)No frequency-division multiplexing 3) Bi-directional transmission 4)Signal travels over short distances Broadband Signalling: 1)Uses analog signalling 2)Unidirectional transmission 3)Frequency-division multiplexing is possible 4)Signal can travel over long distances before being attenuated
What is multiplexing why is multiplexing needed in electronics communication?
multiplexing refeers to the transmission of different signals in the same channel simultaneously. There are many forms of multiplexing that can be used, including frequency division multiplexing(FDM) where individual signals are transmitted over adjacent , non overlapping frequency bands. they are transmitted in parallel and simultaneously in time. In time division multiplexing(TDM) each signal is allowd to use the whole bandwidth for a certain period of time. Multiplexing is needed so that the available channel can be used efficiently and also to save costs. There is too much to know about multiplexing, here is just a short overview. One thing that one has to know is multiple access.
