Which multiplexing technique transmits digital signal?
In analog transmission, signals are commonly multiplexed using frequency-division multiplexing (FDM)
What is a tdma?
Time Division Multiple Access. Or even Time Division Multiplexed Access.
What is frequency domain modulation?
Do you mean FDM or Frequency Division Multiplexing? If so, FDM is the division of a high frequency carrier into separate non-overlaping bands to be modulated by separate inputs. It's the modulation of several low frequency channels onto a high frequency carrier. Voice channels are low bandwidth inputs relative to the broadband carrier used to broadcast them.
What are the CDMA bands?
CDMA-(code division multiple access), uses spread spectrum technique, which spreads the bandwidth of the data uniformly for the same transmitted power.(surce:wikipedia)
Which component translates a synchronous serial connection to time division multiplexed connection?
The router.
How adsl modem carry high bandwidth traffic?
ADSL modems carry high bandwidth traffic by using a technique called frequency division multiplexing. This allows the modem to split the available bandwidth into separate channels: one for upstream data and multiple for downstream data. By utilizing higher frequency ranges for downstream traffic, ADSL can achieve faster speeds while still allowing voice signals to be transmitted simultaneously over the same phone line. This efficient use of the existing copper infrastructure enables high data rates without requiring significant upgrades.
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.
Is FDM is an example of parallel transmission?
Frequency Division Multiplexing (FDM) is not an example of parallel transmission; rather, it is a method of multiplexing that allows multiple signals to be transmitted simultaneously over a single communication channel by assigning each signal a different frequency. In FDM, each signal occupies a unique frequency band within the overall bandwidth, enabling concurrent transmission without interference. Parallel transmission, on the other hand, involves sending multiple bits simultaneously over multiple channels or wires.
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.
Can different frequencies be broadcasted from the same antenna simultaneously?
Yes, different frequencies can be broadcasted from the same antenna simultaneously, a technique known as frequency division multiplexing (FDM). This allows multiple signals to be transmitted over the same medium without interference, as long as the frequencies are sufficiently spaced apart. However, careful design and filtering are required to avoid cross-talk and ensure signal integrity. Additionally, the antenna's bandwidth must accommodate the range of frequencies being transmitted.
How multiple signal transmitted on the same transmission channel?
Multiple signals can be transmitted over the same transmission channel using techniques such as Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), and Code Division Multiple Access (CDMA). TDM allocates different time slots to each signal, while FDM assigns different frequency bands to each signal. CDMA uses unique codes for each signal, allowing them to occupy the same frequency band simultaneously without interference. These methods enhance the efficiency of channel utilization and increase the capacity of communication systems.
What advantages does TDM have over FDM in a circuit switched network?
TDM and FDM are multiple access techniques used for multiplexing number of signals into a single single for bandwidth saving. FDM is older technique of multiplexing whereas TDM is relatively a newer technique of multiplexing. TDM advantage over FDM is that it offers bandwidth saving and there is low interference between the signals that are being multiplexed.
