tdm: total available time is divided into several user
eg: telephone system
fdm: total frequency bands are divided into several users
eg : television broad casting
wdm: total wave lengnth is divided in to number of users
eg: optical networking
These are particular one line definitions of tdm, fdm and wdm but you should realize that there is no difference in fdm and wdm, they are different terms talked in context of radio waves and optical fiber accordingly. As both light waves and radio waves are electro magnetic waves there speed is same so if you are dividing frequency or wave length both are leading to same.

Explain the term mulitplexing and diffreitiate between fdm and tdm?
TDM (Time Division Multiplexing) and FDM (Frequency Division Multiplexing) are two methods of multiplexing multiple signals into a single carrier.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.Summary:1. FDM divides the channel into multiple, but smaller frequency ranges to accommodate more users, while TDM divides a channel by allocating a time period for each channel.2. TDM provides much better flexibility compared to FDM.3. FDM proves much better latency compared to TDM.4. TDM and FDM can be used in tandem.FDM is used in 1st generation analog system whereas TDM is used in2nd generation analog system.
Difference 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.

How the operation of tdm and fdm?
Time Division Multiplexing and Frequency Division Multiplexing. Allows multiple data channels across a single medium by separating the data streams onto different frequencies (FDM), or by sending one stream, waiting, then sending the other stream (TDM).

Application of FDM and TDM?
Hi My name is Mohammed shushiTDM vs FDMTime-Division MultiplexingTime-Division Multiplexing (TDM) is a type of digital or analog multiplexing in which two or more signals or bit streams are transferred apparently simultaneously as sub-channels in one communication channel, but are physically taking turns on the channel. The time domain is divided into several recurrent timeslots of fixed length, one for each sub-channel.Time-division multiplexing (TDM) is a method of putting multiple data streams in a single signal by separating the signal into many segments, each having a very short duration. Each individual data stream is reassembled at the receiving end based on the timing.Time division multiplexing (TDM) and has many applications, including wireline telephone systems and some cellular telephone systems. The main reason to use TDM is to take advantage of existing transmission lines.TIME DIVISION MULTIPLEXING (TDM) allows multiple conversations to take place by the sharing of medium or channel in time. A channel is allocated a the whole of the line bandwidth for a specific period of time. This means that each subscriber is allocated a time slot.Frequency-Division MultiplexingFrequency-division multiplexing (FDM) is a form of signal multiplexing where multiple baseband signals are modulated on different frequency carrier waves and added together to create a composite signalIn many communication systems, a single, large frequency band is assigned to the system and is shared among a group of users. Examples of this type of system include:1. A microwave transmission line connecting two sites over a long distance.2. AM or FM radio broadcast bands, which are divided among many channels or stations. The stations are selected with the radio dial.

Advantages of space division switching over time division switching?
Space division multiplexing uses spacing to separate channels in a communications link. These separations may be done by frequency, insulation, or distance (spacing). Time division multiplexing is one way of doing the spacing separation. Space division multiplexing may use other techniques, such as TDM, FDM, etc., to maintain separation so that the conversations do not collide with each other.

Advantages of STDM and FDM?
Save Time The FDM can reduce the power restoration time by up to 75%, on average. The FDM is anticipated to be 4 times faster than the old divide and concur method, and twice as fast as FCIs. This can certainly lead to happier customers. Save Money The FDM can significantly reduce costs from three primary sources; material cost, installation cost and usage cost. The FDM costs up to 40% less than an equivalent FCI installation. The FDM takes about the same amount of time to install as FCIs, however, a typical loop circuit requires only one FDM installation or 12 or more FCI installations. The FDM can therefore be 12 times faster to install than an equivalent FCI installation. The usage cost savings results from having a remote readout that is read from a single location, rather than tracking down a series of transformers. Improve Reliability The contribution to CAIDI caused by faults in underground cable systems can be improved up to 75%. Significant improvement in restoration time can lead to happier customers as well as regulators. An active reliability program is often a factor the PUC evaluates during rate review.
Is the iPhone compatible with tdm-ip1?
I have tested the iPhone4 using the TDM-iP1 into a Sony STR-DA4600ES receiver using the digital media port and it worked fine for all audio files on my iPhone. The one exception is my music videos. It plays audio only, no video.
