What advantage does a statistical multiplexer have over a TDM multiplexer or an FDM multiplexer?
Statistical multiplexer does not reserve time slots or frequencies. Instead, it dynamically allocates bandwidth only when it is needed.
Where can one measure how much bandwidth they are using?
A simple search of the net will find there are many bandwidth monitoring sites that are available for free. A popular one is callled Free Meter Bandwidth Meter. You also can use WFilter freeware for network bandwidth monitoring.
What are the different types of multiple access techniques?
Tdm, fdm,
Why an overmodulated AM signal occupies a lot of bandwidth?
find dictionary....or contact 999
Does a low bandwidth signal have more power than a high bandwidth signal?
A low bandwidth signal does not have more power.
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.
When FDM is used how many users can be support?
It is based on the band width of the system and bandwidth located to each channel in it.
How much bandwidth is required to send 132 voice grade channels by FDM on an international satellite system?
10MHz
Find the minimum bandwidth for FDM five sources each requiring 400Hz 200Hz guard band per channel?
no of sources: 5 bandwidth required for each source= 400 Hz no of guard times= 5 bandwidth of each guard time = 200 Hz minimum bandwidth = 5 *400 + 5*200 Hz
Why is bandpass filter used in fdm telemetry?
since fdm sends many message simultaneously the message signals must be bandpassed to send through the channel along with the error messages to reduce the bandwidth of the channel

Comparison between fdm tdm?
FDM-Frequency division multiplexing where as TDM mean Time division multiplexing.In FDM spectrum is divided into frequency whereas in TDM divided into time slot.FDM is used in 1st generation analog system whereas TDM is used in 2nd generation analog system.

Answer:- 500MHz From:- Joginder Kumar Network Engineer Datacraft India Ltd.
When was FDM Group created?
FDM Group was created in 1991.
What is the population of FDM Group?
The population of FDM Group is 900.
What are the differences between FDM and TDM?
FDM vs. TDMTDM (Time Division Multiplexing) and FDM (Frequency Division Multiplexing) are two methods of multiplexing multiple signals into a single carrier. Multiplexing is the process of combining multiple signals into one, in such a manner that each individual signal can be retrieved at the destination. Since multiple signals are occupying the channel, they need to share the resource in some manner. The primary difference between FDM and TDM is how they divide the channel. FDM divides the channel into two or more frequency ranges that do not overlap, while TDM divides and allocates certain time periods to each channel in an alternating manner. Due to this fact, we can say that for TDM, each signal uses all of the bandwidth some of the time, while for FDM, each signal uses a small portion of the bandwidth all of the time.TDM provides greater flexibility and efficiency, by dynamically allocating more time periods to the signals that need more of the bandwidth, while reducing the time periods to those signals that do not need it. FDM lacks this type of flexibility, as it cannot dynamically change the width of the allocated frequency.The advantage of FDM over TDM is in latency. Latency is the time it takes for the data to reach its destination. As TDM allocates time periods, only one channel can transmit at a given time, and some data would often be delayed, though it's often only in milliseconds. Since channels in FDM can transmit at any time, their latencies would be much lower compared to TDM. FDM is often used in applications where latency is of utmost priority, such as those that require real-time information.FDM and TDM are often used in tandem, to create even more channels in a given frequency range. The common practice is to divide the channel with FDM, so that you have a dedicated channel with a smaller frequency range. Each of the FDM channels is then occupied by multiple channels that are multiplexed using TDM. This is what telecoms do to allow a huge number of users to use a certain frequency band.Read more: Difference Between FDM and TDM | Difference Between | FDM vs TDM http://www.differencebetween.net/technology/difference-between-fdm-and-tdm/#ixzz1x12BskVn
