What is the difference between time division multiplexing and space division multiplexing?
The difference is the way the data is separated and transmitted between two points. In Space Division the data is separated physically i.e. the carrier medium is divided into different channels. This could be by using different wires, waveguides, optical cables, etc, or by frequency i.e. radio channel, carrier frequency. Time Division uses the same channel in one of the above but different data is given a specific order and location in time for transmission. e.g. Synchronsation followed by type (a) data, then type (b) data followed by a checksum. The whole process is repeated continuously until transfer is complete.
What are the applications of Time Division Multiplexing technique?
All signal multiplexing techniques were invented to permit a single physical communication channel to carry multiple different signals. This reduces the investment costs in physical communication channels: e.g. long distance telegraph lines, long distance telephone lines, microwave links, orbiting communication satellites, fiber optic cable. Time Division Multiplexing can be implemented using either analog or digital signaling means.
Why FDM is for analog signals and TDM is for digital signals?
FDM stnds for frequency division multiplexing and it is used only in case of analog signals because analog signals are continuous in nature and the signal have frequency. TDM-stands for time division multiplexing and it is used only in case of digital signals because digital signals are discrete in nature and are in the form of 0 and 1s. and are time dependent.
When several signals can be transmitted at once it is called?
When several signal transmitted simultaneously. this is called multiplexing of signals.many signal are combined into one and then they transmitted.
What are the purposes of signal processing?
With DSP you can change, modify, study the properties of signals more easily than analog signal processing. You can do modulation, encryption, decryption, encoding, decoding, multiplexing, comparing etc
Which multiplexing technique transmits digital signal?
In analog transmission, signals are commonly multiplexed using frequency-division multiplexing (FDM)
What is downward multiplexing?
Downward multiplexing refers to distributing a single signal across multiple channels.
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.
Why is multiplexing so cost-effective?
Carries multiple signal on a signal medium.
How does code-division multiplexing distinguish one signal from another?
Code-division multiplexing uses unique spreading codes to encode each signal before combining them in a shared channel. These spreading codes allow the receiver to distinguish between signals by applying the inverse code to extract the desired signal while suppressing interference from others. This method enables multiple signals to coexist in the same frequency band without interfering with each other.
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 Integration of TDM signals?
TDM MEANs TIME DIVISION MULTIPLEXiNG, of any transmitting signal , integrating it means combining all the different signals over into a common signal for the bulky transmission of the signals at same channel in same time

What is multiplexing in computer network?
multiplexer is a device that add two or more signal in a single signal in networking
Define and describe FDM?
FDM: Frequency-division multiplexing. A multiplex system for transmitting two or more signals over a common path by using a different frequency band for each signal.
