What happen if the bandwidth of signal greater than channel bandwidth?
distorttion
What was the effect of reducing the channel bandwidth?
lesser data traffic
What is the difference between the channel spacing and the transmission bandwidth?
Bandwidth is the measure of range or band of frequencies that a channel or path can handle at a maximum rate. whereas, throughput is the average rate of successful message delivery over a communication channel. and Goodput is simply the changing in throughput rate.
What is the channel bandwidth for 2KHZ signal?
depends on type of modulation and other variables
Suggest a possible communication channel for transmission of a message signal of bandwidth of 5 MHz?
sky waves
A digital data signaling system is requird to operate at 9600bps If a signal element encodes a 4-bit word what is the minimum required bandwidth of the channel?
C = 9600 = 2B*3 = 2B * 3 W = 1600 Hz
A digital signaling system is required to operate at 9600 bps If a signal element encodes a 8-bit word what is the minimum required bandwidth of the channel?

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.
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 type of signaling transmits call setup on the same channel as a voice signal?
In-Band Signaling (IBS)
What is a telecommunications network protocol?
is the set of standard rules for data representation, signaling, authentication and error detection required to send information over a communications channel
What is In- channel signaling?
In-channel signaling is also often referred to as in-band signaling. See http://en.wikipedia.org/wiki/Signalling_(telecommunications)#In-Band_versus_Out-Of-Band and http://en.wikipedia.org/wiki/In-band_signaling.The signaling used to establish and tear down a phone call was located in the same physical communication channel used to carry the call (i.e voice, fax or modem) traffic, and used DTMF tones. Examples are CCITT Signaling Systems 1-5 R1 & R2. Most books on SS7 should talk briefly about this.SS6 & SS7 moved to take the signaling out-of band, and to establish a common channel for all signaling in digital packet-based format (non-tone based) allowing one signaling channel to control a large number of "voice" circuits.
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 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 .
