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

Advantages of synchronous time division multiplexing and frequency division multiplexing in computer netwoeks?
http://zone.ni.com/devzone/cda/ph/p/id/269
In asynchronous time division multiplexing which bits increase the processing overhead of a system?
The bits associated with synchronization and framing increase the processing overhead in asynchronous time division multiplexing. These bits are necessary for maintaining the timing and alignment of data streams from multiple sources within the system.
Which of the three multiplexing techniques arre used to combine digital signals?
Frequency-division multiplexing, wavelength-division multiplexing, and time-division multiplexing.
What modulation technique used in mobile phones?
Currently the mobiles use GSM(Geo Synchronous Mobiles ) and CDMA(Code Division Multiple Accesss) techniques. GSM inturn uses TDMA(Time Division Multiplexing) or FDMA(Frequency Division Multiplexing) or sometimes both to fit in the required criteria.
Why amplitude division multiplexing is not used?
what is function of amplitude division multiplexing
Which of the three multiplexing techniques are used to combine analog signals?
Frequency-division multiplexing and wavelength-division multiplexing
How can you accommodate faster devices on a network that implements synchronous time-division multiplexing?
Increase the size of the blocks allocated to all devices Increase the number of blocks allocated to these devices
What is the Block diagram for time division multiplexing?
What is multiplexing and its diagram
What is the definition of the word 'multiplexing'?
Multiplexing is the process of combining multiple signals over one media line. There are several types of multiplexing: frequency division, time division, and wavelength division.
Which multiplexing technique transmits digital signal?
In analog transmission, signals are commonly multiplexed using frequency-division multiplexing (FDM)
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.
What is Peer Division Multiplexing?
nothing
