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.


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.


How does an RF cable work?

answ2. An RF transmitter generates radio frequency waves in its circuits, and to this 'carrier signal', it adds the information part by modulating the carrier signal. This composite signal (carrier plus information) is then fed to an antenna (aerial).The aerial induces a corresponding signal into the atmosphere, by altering the Electric and Magnetic fields at (obviously) the same frequency.The impedance of 'free space' is few tens of Ohms to a few hundreds of Ohms.[Impedance may be considered analogous to resistance, but with reactive properties as well.]The power emitted by the transmitter can vary from a megawatt or so (for VLF signals) to a few watts for handheld devices.An Rf receiver receives the signal from the atmosphere, from its own aerial.The receiver aerial is often quite simple, and the signal level is typically of a few microvolts.This it tunes in (gets rid of unwanted signals and amplifies only the wanted ones).The receiver circuits then strip the information part of the signal from the carrier part, and amplify this to a useful level for audio or video.The actual signal into the loudspeaker will be a few tens of volts. In spite of the inefficiency of loudspeakers, (often only a few %) the signal eventually appears at a level that may be heard. A background radio will be a few milliwatts of power.Even a very loud sound is only a few watts of radiated (sound) energy!!

What are the differences between synchronous and asynchronous time division multiplexing?

1) IN syncronous TDM , the multiplexer allocates exactly the same slot to each device at all times , whether or not a device has something to transmit in contrast, in asyn TDM if thedevice have nothing to transmit then its time slot is alloted to another device. 2) synch TDM requires a common clock signal at both the ends ( sender & receiver) asynch TDM dsnt require a comn clock .. 3) if synch has n input lines , the frame contains a fixed no. of at least n TM slots. if it has n input lines , the frame contains not more than m slots where m< n


Why is it that the start and stop bits can be eliminated when character interleaving is used in synchronous TDM?

Because it reassigns time slots and fix it


Why SONET is called synchronous network?

Because SONET/SDH uses "synchronous TDM multiplexer" to multiplexe signals from multiple electrical sources . All clocks in the system are locked to a master clock.


Briefly explain differences between synchronous TDM and statistical TDM?

Synchronous TDM:each input has its time slot preassigned to it , whether there are data to send or notStatistical TDM:-time slots are assigned to inputs depending on demand where multiplexer scan input buffers ,collecting data until a frame is filled and the sends the frame- to recognize the data fields owner , it is specified with header : address and lengthHope this helps , good luck


Why statistical TDM is considered more efficient than synchronous TDM?

A statistical Time Devision Multiplexing is more efficient than a synchronous TDM because it allocates time slots dynamically on demands and doesm't dedicate channel capacity to inactive low speed lines.

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.
