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 bandwidth on a digital signals?
Bandwidth is an inherent characteristic of a given transmission channel, or is determined by the narrowest-bandwidth component of the system. The bandwidth of a channel will limit the possible attainable data rates. This is shown simply by Shannon's Theorem, which states C = B log_2 (1+P_signal/P_noise), where C is the channel capacity in bps, B is the channel bandwidth in Hz, P_signal is the power of the detected signal in W, and P_noise is the noise power of the detected signal in W. As an example, consider a standard phone line (i.e., using a dial-up modem). Standard phone lines have a bandwidth of about 3.4 kHz and a signal-to-noise ratio of about 10,000. Using this information, we get C = (3.4 kHz) log_2 (1+10,000) = 45 kbps. Dial-up modems can actually get as high as 56 kbps, but that is beyond the scope of this question. In general Shannon's Theorem can provide a fairly accurate way to predict the possible data rates for a given transmission channel if the bandwidth and resulting signal and noise powers are known.
What is the relation between the bandwidth and symbol rate?
the channel capacity (information in bits per second) is related to bandwidth and SNR by the relation C= B[log(1+SNR) b/s log is at the base 2 B= bandwidth of a channel C= capacity in bits per second SNR= signal to noise ratio.
What is the transmission time of a packet sent by a station if the length of the packer is 1 million bytes and the bandwidth of the channel is 200 Kbps?
Divide 1 million by 200,000 and the answer is 5 seconds.
What are two primary communication resources?
transmitted power and channel bandwidth
A communication channel with additive white gaussian noise has a bandwidth of 4kHz and SNR of 31dB. Its channel capacity is?
20kbps
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.
Difference between channel and bandwidth?
a channel is actually a path through which a signal of a particular frequency travels and bandwidth is the capacity of that path it tells about the number or range of frequencies which a path can carry
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 .
Suggest a possible communication channel for transmission of a message signal of bandwidth of 5 MHz?
sky waves
What is the role of multiplexers in signal transmission?
A multiplexor is used to encode multiple input signals for transmission over a single channel. This works because the bandwidth of the output channel is higher than the bandwidth of the input signals, allowing the input signals to share the output channel. At the other end, a de-multiplexor decodes the channel and decodes the individual input signals.
What are key factors that can affect channel capacity?
Channel capacity - It is the rate at which the data can be transmitted over a given path, or channel, under the given conditions. Key factors affecting the channel capacity are- Data rate- speed of data transmission measured in bits per second. Bandwidth – Maximum. Bandwidth, noise, and error rate.
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 the difference between the ocean the sea and a sea channel?
what is the difference between the ocean the sea and a sea channel
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 is the difference between a channel and a medium in communication?
the difference between channel and medium is that channel is the form how the message will be while medium is the actual message
What is the difference between a channel and link?
The word link refers to the physical path. The word channel refers to the portion of a link that carries a transmission between a given pair of lines. One link can have many (n) channels.
