What is demultiplexing?
Demultiplexing is to separate 2 or more channels that have been multiplexed. Signals are typically multiplexed or combined onto one higher speed channel to efficiently use the bandwidth.
What is the speed of an OC-3 connection?
An OC-3 circuit's bandwidth capacity per full port is 155.52 Mbps. This of course is if you dedicated it to one source. If it is divided and multiplexed, you will have to note there will be less bandwidth per channel.
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
What is the difference between transmission bandwidth and channel bandwidth?
The transmission bandwidth refers to the range of frequencies that are being transmitted from one point to another. The channel bandwidth on the other hand refers to the frequencies of a given channel.
Which is more usefull a multiplexer or a demultiplexer?
One is useful without the other. Data that is multiplexed at one end of a communication channel must be demultiplexed at the other end.One is useful without the other.

What is the effect of reducing the channel bandwidth?
I'm afraid you will need to specify on what exactly are you referring to. We could be talking about a radio channel bandwidth, a computer data transfer channel bandwidth or even a radio communications channel bandwidth. It is difficult to tell with the narrow question you posed.
What is Low pass channel and band pass channel?
Low pass channel or medium with the bandwidth that starts from zero.Band pass channel has the bandwidth that does not start from zero.
WHAT IS coherence bandwidth of radio channel?
The coherence bandwidth of a wireless channel is the range of frequencies that are allowed to pass through the channel without distortion.
What happen if the bandwidth of signal greater than channel bandwidth?
distorttion
What is the difference between wideband and narrowband?
In the Narrow-band channel the signal see the channel as a flat channel , and the signal pass the channel without any type of cut . In the other hand the signal that passes through the wide-band channel see the channel as a frequency selective channel and cut values from the signal . I mean that if the bandwidth for the signal is lager than the bandwidth for the channel then, the channel is a wide-band channel, and if the bandwidth for the signal is smaller than the bandwidth for the channel then the channel will be a narrow-band channel .
