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 SDM typically realized and combimed with FDM?

Statistical Division Multiplexing (SDM) is typically realized by allocating time slots to different users based on statistical multiplexing techniques. This allows for more efficient use of available bandwidth by dynamically assigning resources based on user demand. When combined with Frequency Division Multiplexing (FDM), SDM can further increase the overall capacity of a communication system by simultaneously multiplexing signals in both the time and frequency domains. This combination enables even greater flexibility and efficiency in managing multiple users and their data streams within a shared communication channel.


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


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.

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.

What is the transmission over a wire that can carry multiple signals at once?

The transmission over a wire that can carry multiple signals at once is known as multiplexing. This technique allows multiple data streams to be combined and transmitted simultaneously over a single communication channel, maximizing the use of the available bandwidth. Common methods of multiplexing include Time Division Multiplexing (TDM) and Frequency Division Multiplexing (FDM). These methods are widely used in telecommunications and data networks to enhance efficiency and throughput.
