What happen if the bandwidth of signal greater than channel bandwidth?

How do you find bandwidth by fdm?
To find bandwidth using Frequency Division Multiplexing (FDM), you first determine the frequency range allocated for each channel within the system. Bandwidth is calculated by subtracting the lowest frequency of the first channel from the highest frequency of the last channel in the multiplexed signal. Additionally, you should account for guard bands, which are unused frequency gaps between channels to prevent interference. The total bandwidth is the sum of the individual channel bandwidths plus any guard bands used.
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 meaning of 56 MHZ bandwidth microwave channel?
A 56 MHz bandwidth microwave channel refers to the range of frequencies that the channel occupies, specifically 56 megahertz. This bandwidth determines the capacity of the channel to transmit data, with wider bandwidths allowing for higher data transfer rates. In microwave communication, channels with larger bandwidths can support more information or higher quality signals, making them suitable for applications like broadband internet and telecommunications. Overall, the bandwidth is a critical factor in the performance and efficiency of microwave transmission systems.
What is the channel bandwidth for 2KHZ signal?
depends on type of modulation and other variables
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 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 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 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 effect on bandwidth due to positive feedback amplifier?
bandwidth decreases
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 .
What is the typical bandwidth of a channel for a cable modem?
6 MHz
What are two primary communication resources?
transmitted power and channel bandwidth
How much minimum bandwidth is required for multiplexed channel?
The minimum bandwidth required for a multiplexed channel depends on the number of channels being multiplexed and the bandwidth of each individual channel. In general, the total minimum bandwidth needed is the sum of the bandwidths of all the channels being combined. For example, if you are multiplexing four channels, each requiring 1 MHz, a minimum bandwidth of 4 MHz would be necessary. Additionally, some multiplexing techniques may require guard bands to prevent interference, which would increase the total bandwidth requirement.
