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.

The channel used in a digital communication system is used to convey an information signal. A channel has certain capacity for putting in information that is measured by bandwidth in Hz or data rate.
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.
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.
Low pass channel or medium with the bandwidth that starts from zero.Band pass channel has the bandwidth that does not start from zero.
The coherence bandwidth of a wireless channel is the range of frequencies that are allowed to pass through the channel without distortion.

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.
bandwidth decreases
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 .
